I don't know how, but somehow these cheats even manage to by-pass the AGP blacklist - SCARY!...
I had one in TODAY'S submissions from woodencock.com (Kirk Levings) and I checked: it's in my domain blacklist for day's!
Now, I enter them as above: domain.com - no
http://, no
www.domain.com, simply the domain-name because before I found that the blacklist was circumvented by changing
http://www.domain.com to
http://domain.com or using a sub-domain like
http://tgp.domain.com.
