501 Error at...

Is this your domain? If not you should buy a domain and work on the blog a bit. Their are ads in weird locations, also some other issues like breaks where they don't belong. A better theme would be nice, but the site needs allot of work. If you need a warning page then cut down the amount of text to be a single line (Like "This is an Adult Site, if your not an Adult then Get The fuck out! (Agree) (Leave)"
There are allot of other problems, it really needs some work. You can spend allot of time promoting the site but if people get to the warning page and see's that it is messy and has errors they will leave.
If you start changing things then I will post more changes, but so far it doesn't seem your taking any advice given.
