Yes, this would be frowned upon.
Essentially having multiple accounts is fine if you don't do anything with the combination of the accounts that you can't do with a single account. The most obvious example of this is voting on your own posts: you can't upvote your own posts, so using another account to upvote your posts is bad. (Very bad.)
Asking more ...
I have in mind users who wish to ask a large number of questions in a short space of time (perhaps in the run up to exams for example) and thus will exceed the default question limits.
This is against the rules. In general, multiple accounts are permitted as long as they are not used to do anything a single account cannot.
You can have as many accounts as you'd like. But they must act as one. In particular, what you wouldn't do with one account, you shouldn't do with the other.
It's not that it's against the rules as much as it is a type of self promotion that is not great.
So overall, please don't do that.
Well, the only particular rule to abide by if you have multiple accounts is:
Don't use multiple accounts to do anything you couldn't do on a single account.
A particular application of this rule is that you should not avoid any rate limits using two accounts - so, if one account is prevented from asking questions, circumventing this with another account ...
The reason for a ban is mainly to stop a problematic behavior. If somebody returns and the behavior is so different (and non-problematic) that nobody even notices I think it is almost a non-issue.
In the present case, the behavior of the account became problematic pretty quickly. That it was a ban-evasion was just "icing on the cake" but not the only or ...
It is allowed to have several accounts as long as you do nothing with those accounts that in essence you could not also do with a single one.
Some examples of things not to do:
Do not use a new account to evade a suspension or ban.
Do not vote for posts of your other accounts. Best, try not interact with posts of your other accounts at all.
Do not use ...
Flags used to be the right tool. The moderators could have merged the accounts and the OP would have regained control of their account.
But now they can't do that anymore.
Now you need to explain to the OP that they should register to the site, and then they can request the account to be merged. And if they don't want to do that... Well, too bad?
The Complete Rate-Limiting Guide on Meta Stack Exchange lists the 50 questions per 30 days limit, and while it's not explicitly mentioned for this particular rule, a similar rule for 1 question per 40 minutes has the following remark:
This applies to the user's IP address, not their account. If the user shares that IP with other users, they can be limited ...
It is not possible to transfer points from one SE site to another. However, there is the "association bonus" which at least allows for a start at 101 level instead of 1, and thus gives commenting and some other privileges right away.
Fundamentally, knowing one community does not say much about how one will fare in another. We can and do assume that ...
I declined the flag because there was nothing to be done. We can't merge accounts or move rep from one account to another at leisure.
Also, if I may be so bold, I thought the issue was too minor to waste time fixing. There are more important things to worry about than if an unregistered account misses out on 10 rep and unintentionally gains 6 through ...
The question was asked by an unregistered user, and the account seems to have "split" (and a second account was created).
The original question was asked by a user account with 16 points; then answered by a different user account (which likely belongs to the same user) and it only has 1 point.
If you look closely you'll see that the case of 16 points it ...
The basic rules are:
One can have more than one account.
One must not do anything that one could not do with one account.
This means it is not forbidden to engage in meta with a "second" account, especially not if one does not with the main one.
I personally would advice against it except in special circumstances. Something I would find alright ...
Is there any reason why there cannot be a viewable record when someone registers under a different alias? (...)
There are no privacy issues, right? If I know that arf-arf = rapstar no one's privacy is compromised.
A very large privacy issue comes about when one account is clearly tied to the user's identity, while another account is used for anonymous ...
Normally, yes. Substantial unauthorized additions to other users' posts should be reverted.
However, the two users here are clearly controlled by the same person -- they have the same gravatar. No action is necessary.
This might explain the differences you are seeing. Note that when you view a random tag by newest the questions are sorted according to asking time, and the account shown will be the account used to ask the question. Looking at it by activity shows the questions sorted by last activity time, and the account shown will be that which last made an action (e.g., ...
There are technical measures in place to make this difficult. As posted on Meta Stack Exchange,
Can I simply create a new account?
No. The automatic ban is at a lower level than account.
There isn't much of any information available about what "lower level than account" means. The details are intentionally kept secret by SE, to make it more ...
