Be very careful

I really hate having to make a journal entry regarding this, but I was just viciously harassed for refusing to take a commission (even though it states blatantly on my profile that I don't do that) and thought it would probably be a good idea to warn others. Just read the most recent conversation in the comment section of one of my Balto fanpieces The Whole Brood and you'll see exactly what I mean... I noticed he seems to be doing this only to artists who don't take requests/commissions/etc. and knowing that a lot of my friends/watchers fall into that category, I was naturally worried. The strange thing - besides his apparent "nightmares" that only seem to happen when somebody tells him "no" - is the fact that this nutjob isn't even a watcher of mine and yet he somehow "knew" me and felt this necessary :/ I'm pretty pissed off and upset but more shaken up than anything else, I blocked him of course but now I'm worried about everyone else - even if he doesn't try to "retaliate" against any of my friends like most of these types of psychos do, I can't help but feel for the other artists he could be potentially harassing (I already know for sure that he's moved on to one canine artist, leaving her the same incoherent nonsensical garbage in her comments)
I really don't want to make anything out of this, I just want everyone to watch out - if you get any random watches or strange comments from that username, just block them immediately for your own sake.
