Hi folks
I have had a few domain names for a couple of years now. One site which I was planning to redevelop (a poker site) has a fourm on it which I has been hijacked by porn spam.

I just happened to look at my web stats because I was planning on selling a couple of my domains when I couldn't believe my eyes. 12000 unique visits last month and averaging 5000 since the middle of last year

.
I am a complete newbie at this stuff but what should I do. Should I sell the domain?
it is a co.uk site any idea what it might be worth?
