offensive new forum member

The admins here are very good at what they do, so I doubt I even need to bring attention to this, you guys and gals are probably already covering it, but ...

A relatively new forum member by the name of "kiligian" has been repeatedly abusing this website.

First, he posted a rather obvious lie about hearing the new Dream Theater album in this thread:

Ok, maybe not real abuse yet. Then, he started a thread (the same day!) about how he's heard the new Porcupine Tree album, again a fairly transparent lie:

http://www.progarchives.com/forum/forum_posts.asp?TID=36179&FID=3

But his little fun & games with this website continues. You may argue "He has heard the albums and you are slandering him by accusing him of being a liar." Fine, I'll accept that. However, in the same Porcupine Tree thread, he responded to well-reasoned criticism with this enlightening statement:

"whatever i post my reviews in swedish we have out own way of puncutation over there we write diffrently so ha take your opion shove it up your arse.."

Now, I'm not particularly well-versed with the forum rules, my apologies for that, but telling another forum member to "shove" something "up [their] arse" is likely to be frowned upon around here.

I don't know what action is appropriate, and I'm not suggesting any particular course of action, I just wanted the admins to be aware of the issue.
