Answers (and questions) containing email addresses are suspicious too.
There is no need to provide your email, and it is easy to filter these out.
Another option is to search for swearwords. I have seen them, but never in good answers. But of course we shouldn't make the clbutic mistake.
And don'nt forget the word noob with possibly a repetition of n, o and b and sometimes ending with s. (like noooooooooobbbbb).
