Hello Discipulus,

I agree with you, I have noticed that many monks post an answer anonymously and also this is an open forum and people should express their opinion even if some people just spend time to comment in an insulting way the OP.

On top of that, I was thinking that by restraining the Anonymous Monk on commenting on questions, how he/she would comment on his own question. I mean let's assume that Anonymous Monk is asking a question and there are some replies but yet he/she is not clear about the answer, how he/she would be able to comment after?

So I think my idea is not applicable for many reasons. A better approach would be as you suggested to use key words to detect malware comments.
