I have been suspicious too - hard to pin down exactly, but the mix of questions and the non-serious style make it hard for me to interpret the questions in good faith.
I agree. In addition to 6 or so closed questions that clearly fail the FAQ test, there was one more (about anorexia) that was so much off the mark that it must have flagged as spam and disappeared. The user hasn't responded even a single time to various comments left by a variety of mathematicians. This is getting past tolerable levels.
What's the minimum reputation needed to leave comments on your own question, or on other people's answers?
jbl is correct. You can always leave comments on your own posts or on answers to your questions.
