From
this page I can tell that they use the user name of "layla8540" to spam on forums. I managed to find this page from my referral logs, the page I linked to contains a list of forums to spam either manually or to be used in conjunction with a forum spamming software.
I'm thinking that this person won't be too happy about alot of people submitting DMCA complaints due to this list and/or contacting their host.
I would do a quick search for this name on your forum & take action.
Here's some contact info for their host

Send them an email & translate it here

Also if you have akismet/glowhost spam-o-matic installed, this particular spammer managed to register but the posts do get put into the moderation queue.
