The comment you sketch is fine. This is not what is meant. What is meant is that one should not post "Thanks!!!!!!!!!!", "This is so interesting.", "Best answer ever!" on every other good post one comes across. Imagine a post with score 14 where every user that up-voted the post also commented "Thanks; nice answer." It would be a bit messy. Note that ...

You should flag for moderator attention and explain what's up. Mods can check the history and see even those things which have been deleted. You should absolutely not engage with that user in any other way. Let moderators handle exceptional incidents like this. Just flag, walk away, and continue to Be Nice on your own.

A joke here and there is alright; if somebody minds they can flag as "too chatty" or "not constructive". One should not overdo this though. It is also important to keep in mind that humor and irony often do not go over well in written and over language and possibly cultural difference. Moreover, when you notices somebody does not like your remarks leave ...

Welcome to MSE This is based a comment Arturo used to add to questions of relatively new users (although this post has been edited a few times and the message has been slightly modified): Welcome to math.SE: since you are new, I wanted to let you know a few things about the site. In order to get the best possible answers, it is helpful if you say in what ...

It was discussed before (although mostly in the comments, if I recall) that there is no problem with people being polite. Often, when users come from SO or other sites on the networks they think this should be removed (because it says so in the network-generic-FAQ). My rule of thumb is that if there is no substantial corrections (grammar, formatting, etc.) ...

I think your answer is fine - setting up the subtraction could certainly be sufficient to help someone with this problem, especially since it should be fairly clear to them where those numbers are coming from. It's clearly a serious answer. However, AvZ does raise a valid objection - but I'd read that more as a stylistic thing (best resolved by AvZ writing ...

Let me begin by saying that I'm not disagreeing with quid. Generally, comments with "Thanks!!!!!" are entirely useless. The "guideline" that you cite, is a network-wide guideline, and the MSE culture is a bit different. At least for now. However, if you asked a question, and someone answered it, it is completely reasonable to post a thank you comment. Even ...

No, it is not abusive to downvote for no stated reason.

How to write math This might be added as a pointer where to find help: For some basic information about writing mathematics at this site see, e.g., here, here, here and here.

Accepting answers After you ask a question here, if you get an acceptable answer, you should "accept" the answer by clicking the check mark $\checkmark$ next to it. This scores points for you and for the person who answered your question. You can find out more about accepting answers here: How do I accept an answer?, Why should we accept answers?, What ...

If the question is tagged homework, I will post hints as answers, since I hate questions showing up in the "unanswered" queue despite being fully resolved in the comments. If I strongly suspect the question is homework, I will post hints as answers to discourage others from spoiling full solutions. Otherwise, if the hint is very short and I expect others ...

Your post leaves many important details open. Some questions follow: How are the answers? Are the answers that are being upvoted any good? If they're not good, then this is an issue indeed. If the answers are good -- could these upvotes be deserved? So: are you sure this is an incident of mutual tactical serial upvoting? Is the symbiotic relationship of ...

Some notes in the form of an answer. Moderators cannot invalidate votes. Any votes. Ever. (And those downvotes I received on that answer were certainly not appropriate! Why can't I invalidate them!? Why!?) We're trusted with a lot of information and tools, but SE still likes to keep certain things out of our reach. Invalidation of votes is either done ...

Also when writing a comment it explicitly states to avoid comments like "thanks" or so. Based on what I've seen, it's more a warning because some popular questions would net hundreds of such comments from others viewing them. I feel like that rule is more lax in terms of the asker saying it to someone else; I know I've done it a few times. I guess the only ...

This question is of insufficient quality (Template arose from this thread) If necessary, this can be preceded by Hello, welcome to Math.SE. Your question is phrased as an isolated problem, without any further information or context. This does not match many users' quality standards, so it may attract downvotes, or be put on hold. To prevent that, please [...

The whole point of stack exchange is to build a high quality collection of questions and answers for a given subject. If you think of things in these terms, it is irrelevant how old a question is. If you can improve the corpora with a better answer, add it.

There is a discussion on meta.SO about this. While all the answers and comments are interesting, the answer given by Jeff Atwood, one of the two creators of the StackExchange network, says that people do not need to explain their downvotes (or at least, not enough so that they face any repercussions from not doing so), but a reminder that one can explain one'...

In comments, as in chat, when a string has more than 80 characters without whitespace, the editor adds whitespace (\unicode{x200C}\unicode{x200B} Zero Width Non-Joiner, Zero Width Space). If you get lucky, the whitespace is added in a place where it does not cause a problem. However, most of the time, it breaks a keyword, control sequence, etc and corrupts ...

It really depends on the situation. Sometimes asking "what have you tried?" is indeed useless. However, a lot of time it does give us some useful information. By showing what the questioner has tried. One get a grip on the questioner's level of mathematical sophistication. One can taylor make an answer which the questioner can understand. Another very ...

It's perfectly fine in my opinion (and judging by what I see on MSE, by the majority of people's opinion). In fact, I'm pretty sure this is the intended use of the comments feature: Use comments to ask for clarification or add more information. If asking for clarification on other people's questions wasn't okay, you wouldn't be presented with the option. ...

Your Comment contained a link to an older Question. Although this Question was not the final target chosen by voting to close-as-duplicate, someone may have voted to consider that target the duplicate, or the system may have identified that link as a duplicate of the target that was eventually chosen. What is known is that when a vote to close-as-...

The procedure used by the Crusade of answers, which specializes in trying to reduce the unanswered questions queue, is a synthesis of the aforementioned strategies: Consider if there is a legitimate reason to vote to move/delete/close the question. If not, ask the commenter using the @ feature to convert his/her comment to an answer. If there's no response ...

No, it's not. However, you should mark any such answers as Community Wiki, so you don't gain reputation from someone else's work.

24

Yes, this is the idea. As long as you have not reached 50 points, you can only do posts (questions and answers). An answer should be an actual answer to the questions; it can be a partial answer too, but it should be substantive. The reason why you cannot tell users what is wrong with their work is that, as unfriendly as this may sound, "we" first want ...

There's no written policy (until now, I guess), and each mod has his or her quirks (so the discussion below is guaranteed to apply only if the handling moderator is yours truly). While you asked about "not constructive", let me be more ambitious and answer in the greatest generality. Before saying anything else, let me first say this: Moderation on each ...

Delete your comment, flag any associated comments for deletion. A toy example: User 1: "I think there is a mistake on the third paragraph. Not every $X$ is a $Y$!" User 2: "Sorry, I don't understand. Isn't every $X$ a $Y$ when we are in a $Z$? User 1: "No, that only holds for specific $Z$'s." User 2: "Ok, thanks!" All such comments ...
