I noticed the creation of tags "delete-me" and "troll," see https://math.stackexchange.com/tags?tab=new for the moment.
I do not know where the latter was used, but I flagged the question where the former was used, so I agree with the message in that case. Still, I am wondering if it is appropriate to introduce such tags.
Is there any established etiquette on marking (by users other than OP) via use of tags inappropriate questions?
If not, what should it be?
