Recently Math.SE has had a spate of questions by Dr. Terry Allen. These questions involve topics like music topology and manifolds formed by sums of functions. So far, the "new" Dr. Terry Allen has had every single one of his questions closed. I don't mean to be offensive but can the moderators just delete such questions outright? This guy seems nothing more than a troll/crackpot and is not welcomed here.
My bad. I should've suspended the user earlier, but I was counting on an "automatic" feature to kick-in, which turns out to likely not be available here.
The user has been temporarily suspended, which will for the time being stop the flood of questions. I personally don't feel the need to actively go in and delete those questions unilaterally. High rep users (and other mods) can vote for deletion if they feel differently.
Also, a side note about flags (since flags are anonymous I don't know if you flagged or not): if you feel strongly that the content is not welcome in our community, there actually is an option under "flag" for literally "It is not welcome in our community." Like "spam" flags, sufficient number of those from users will automatically close and delete a question. That tool I think is the most effective countermeasure against floods of bad questions in the short term.
