However, if you visited the site through Internet Explorer you could have received a trojan. It is not a keylogger by itself, but if left on your computer long enough it could force your computer to download more viruses without your knowledge. It also allows someone to remotely access your computer and potentially hijack it.
According to Bigrat it is pretty obvious if you got it (crashes the browser), but regardless I would recommend that you run a virus scan if you clicked the link. The thread with the link has been removed, and if you did not click it you are fine (it was just an external link).
Information on the particular trojan can be found here
