Why not...it would make your moderator Jobs very easy. you could blacklist the word http://www.fashiongoods.us* and stop loads of spam, and after awhile unblock it.
Its doable, but I'd do it with limitations, as per discussed with Ketola: 1) No "foul" words or anything like that added to the list. 2) Each term/phrase stays on the list max 2-4 weeks. 3) It'd seem that the posts with the words would go through, but they'd get to some kind of whitelisting queue where admins / mods would have to approve/reject posts in that queue (as otherwise spammers would simply change one letter in the string to get past the blocks).
its just the spam is getting ridiculous and its from the same people over and over again. it doesn't have to be an outright blacklisting, you could add the word to a list so every time someone coins the word www.fashiongoods.us* it automatically pops up in an site administration page. this method could be used to scale results and identify repeat offenders. which im pretty sure your report to mod button does(with the potential to be abused). its up to you guys, whatever you want to do.
Why would you EVER allow that site to EVER be posted again? I guess you could lift the ban in 10 years. So I am not the only member angered by their tactics. As a member I am outraged moderators need to be on garbage detail instead of moderating. This is something that will get worse not better unless you implement something to put the breaks on blatant spamming. Now they are http://www.fashionsports.org They needed to change their URL. They will continue to change their url but I think the process is not working well for them. I prefer limiting the number of threads a newbie can post until they have made several posts over several days. That might be much harder to implement than the black list but will be much harder to defeat.
As a potentially better solution than a blacklisting based on words (they'd resort using bit.ly & co instead or add commas, typos, spaces, etc to the addresses), now _all_ news comments, QA questions and QA answers by Newbies and Junior Members are screened automatically by aKismet (the anti-spam solution we use for non-registered users -- if you've noted, 99% of the spam that has arrived lately, is actually from registered members..). This should cut down the spam. Should be noted that this hasn't been throughly tested, so _PLEASE_ report us any bugs you might find that could relate to the change described above.
