Image verification really sucks
 
Hi. Sorry that this is my 1st post, but I just signed up and it took 5 attempts. I could only sign up once there was no doubt if I was being presented with a capital "H" or capital "K". The image verification makes these 2 letters indistinguishable - you may wish to remove them from the available characters.

Cheers!

Nicholas

I think this is normal. I myself had this problem dozens of times on other sites where I couldn't distinguish between 1 and l or o and 0...
But there's nothing you can do about it if you don't want to open up all your forms to spam robots... :(

I agree with this. I run a vBulletin site and I am planning to upgrade from 3.5.3 to 3.6.5 to overcome this problem. A much better image verification exists in the 3.6.x train.

What I do not get is how they are still postig spam on this forum?

I know that "captcha" is hacked, but are that many programs allready using this "captcha" hack?

Also.. It looks like most spam is always in the ISPconfig forum... Why is this?

Its really abit strange that nearly all spam is in the ISPconfig general forum. maybe they scan for the word "General" in the forum name?

Another possibility might be that these spams are from poeple paid for re3gistering to a forum and spamming and not from bots??

I have the same problem, but the script kiddies can bypass captcha and other "anti-spam" measures...I have installed them all.

After going to a captcha-based image verification system, my spam registrations went from 10-15 a day to 1-3 a day immediately. It works, but it's not perfect.

I've read that the captcha has become more difficult to crack in vBulletin 3.6. But we're using 3.5.4.

I run a phpbb forum and it gets quite a bit of spam so i made a little filter and searches there profile for dogy websites and intrests becuase most spam bots are stupid enough to put that in there profile, and it has been very effective:)
