How did this user amass more than 2k worth of reputation?
I have seen this user posting many low quality/off-topic questions.
Many of these are getting closed and subsequently deleted.
Out of his 80 questions, about 40 are closed, though there are several that have been highly upvoted (over 5 upvoted). But from the amount of questions asked, it appears to me that it is more by chance that he post some good questions.
I have posted a comment on one of his (now closed) questions asking why he is posting such question, but got no reply.
What can we do about his activity? Should he be post banned?
