Guys, this software cannot be beaten by a bot, that is if you change the pics. The Russian X-rumer mob "broke" the original default images, they shared the files with other spammers and their software can defeat it. The spammers have support forums like we do, and they update their spam software to defeat things like captcha's.
It's not much trouble to upload new ones one at a time and delete the old ones, do it. I haven't had a bot get past my custom images in a year now since I changed the pics, and 99% of spam is delivered by bots. Blocking the bots mean your registration load is much lighter and you can run those IP's, email accounts and usernames through a spammer database.
Before I got this software I had to manually run every registrant's IP, email account and username though a spammer database, then ban them before they got a chance to post any spam.
This software eliminates that, except for the rare human spammer who registers. I can honestly say that I never had to remove a single spam post since my site has been up in the entire 2 years.
