Two weeks ago the algorythm used in PHP GDK for human verification (you know, the squiggly letter) was finally cracked. The result is now we're getting inundated with bots. I'll need to up the paranoia on the spam filters it seems as they are only really meant as a second line of defense.
Another more asinine solution is to forbid new posters from creating new threads until the account is 1 month old or they make new posts.
I'll think of something. As I said along with a few explicatives on www.nutkinland.com - two can play the script writing game.
That's not the reason. This type of spam is known as comment spam. The primary motive of the spammer is to get a link reference to be followed from here to their site so that Google is tricked into ranking their pages very high. Unfortunately for them all the links created by the URL tag at ENWorld have the rel="nofollow" protocol, meaning the google spider knows to NOT follow the link - hence they are wasting their time. However since they've now defeated the human verify system they can program a bot to make the posts ad naseum until their banned.
These bastards took away the USENET and Spammed it beyond usability in the late 90's. They're gonna try to do it again to forum software - but this time we have an edge. We control the medium of transfer. I can and I will write the software necessary to thwart these attacks using a combination of blacklists and Bayesian filtering and other techniques.
Nimrodical spammers. Can't you do a trace and track em back to point of origin or something? You can report those idiots to someone, I forget who though. ^_^
Darnit.... In any case, you mods and programmer guys do a great job in keepin those spammers out. Tis a pity they are evil, inconsiderate jacksonballs. (Being grandma friendly here is tough sometimes.... )
