Edit:
I am not reopening the question, but note that currently there is a question written in the distinct style of the resident troll and it has so far attracted 4 answers, 3 from our top users.
End of Edit
I created a tag for trolling. Not sure if this is the proper way to deal with this situation, I can see the tag being abused. Please advise if you have concerns. I also do not object to others deleting the tag if they strongly disapprove of it.
Having the tag could make it easier to identify recurring questions.
Seems to me that some people misunderstood my proposal, which was not to create a new category for low quality questions (no one should be declared a troll for asking a poor question) but to tag the repeated questions of a few users, so people know them from a mile away. Anyway, the tag has been deleted, and I will not recreate it.
