This question was edited fourth times by the same user. The edits were minor, rather unnecessary, possibly made for gaining some points. One of the last edits replaced the abstract-algebra
tag by prime-ideals
(btw, a really unnecessary tag). I flagged this as "An unnecessary edit by removing a suitable tag." and the mods say: "declined - a moderator reviewed your flag, but found no evidence to support it".
Another question was edited by removing the graded-rings
and graded-modules
tags, replacing them by algebraic-geometry
only to reflect a hint given into a comment by the editor. I also flagged this as "What's wrong with the graded-ring/module tags?" and the mods say: "declined - flags should only be used to make moderators aware of content that requires their intervention".
I'm intrigued by all these and I really want to know if there is something wrong with my flags.
No need to mention that if you intervene and restore the suitable tags, the mods promptly warn you to stop entering to edit wars: "Please do not get into edit wars over tagging, as that only causes noise in the site. Flag for moderator attention instead."
