Why is not advisable to remove spam links? such as the following:


I removed the URL but for some reason it has been put back.

And also I noticed that the tag 'pi' has been put back, but I had removed that tag.

    $\begingroup$ I don't think that link is a spam (undiscriminated bulk advertisement). In fact, the link is used as an argument for the OP to consider π harmful. $\endgroup$

    $\begingroup$ Look here, math.stackexchange.com/questions/tagged/tag-removed tag-removed makes it easier to avoid coming rubbish when you are searching. It's useful to detag these sorts of questions then. $\endgroup$

  • $\begingroup$ @muad: If this question is so bad that it should not come up in search results for the pi tag, then it should be deleted. But I think that the question, regardless of its quality, is definitely about pi. $\endgroup$

If a question or answer does contain a spam link, please remove it.
In this case, it appears that the link is being used as a reference for a question, and indeed, the text of the question:

Reading the post by Michael Hartl, it sounds rather convincing. Taking circumference to diameter ratio, as opposed to radius, looks like a historical mistake.

Do you have other opinions? Welcome to the community wiki.

seems much less useful without the link. Anyone who wants to answer such a question will likely end up searching for the same link themselves.

Now, if the question itself is just a spam question intended to promote the tau manifesto site, that's a different story. I don't see any reason to conclude this yet. It seems plausible that this is a real question that someone wants to know the answer to.

As for retagging the question tag-removed, any question that is so bad nobody would want it to come up in their search results is best deleted. For example, a question that is so off-topic it fits no existing tags, and was mistagged by the person who asked it. Vote to delete such questions, or flag them for a moderator to delete.
