Well, fine, but you're probably wasting your time, since he changes identity at least daily.
By leaving his subject intact and quoting him in your post, you're also wasting the the time of those of us who have set up up NP filters so that we don't have to see him, since you're broadcasting his filth again for him.
Please don't respond to trolls, and certainly don't quote them, either in your subject or in your text, because that simply adds to the problem.
Cheers,
Frank
