I've come across a user by the name of "professor Jeff" repeatedly these days, and this person keeps posting questions with nonsensical titles and paragraphs talking about "flying disk and timing box" (such as this one). I would post some other examples but I think they have already been deleted by the Math.SE moderators.
My question is: What is Math.SE doing about users like these who repeatedly make accounts with the same name just to talk gibberish like this? Do we ban specific IPs after the first several occurrences? Do we make a filter that search for specific texts (in this case, "flying disk and timing box") and prevent users from making posts with those words?
I'm not trying to sound cynical, and I'm sorry if I do. I just want to know how Math.SE is handling situations like these. Because clearly, users like "professor Jeff" are ruining everyone's time in this great website. Thanks in advance, and sorry if this post sounds so unprofessional... this is my first one here in the meta!
