vBulletin 3.8 - worst for spam.

[Bellardia]

I tend to find recaptcha to be less accurate.
It allows a certain fudge factor when entering words with similar looking letters. If you try, you can purposely enter two wrong words and it will verify, as long as the letters you entered look similar. Try replacing e with o and r with n etc.

Agreed Bellardia,

The best spam prevention i've seen is using the built in akismet filters and the human verification question and answer methods.

I've used that setup on numerous forums to stop automated spam dead in its tracks

I even searched the page (using firefox search feature) and there is not a single mention of ReCAPTCHA in the article you linked to.

Why would you link to an article claiming it mentioned ReCaptcha when in fact it does not? There is a difference between captcha and ReCaptcha.

If you have proof supporting that ReCaptcha (not captcha) has been cracked, please post a link. But make sure that the article does in fact mention ReCaptcha.

Well, lets not split hairs here. Does ReCAPTCHA claim to be any more secure then any other CAPTCHA? Because all I've ever seen it claim as it's sole difference was it helped to digitize literature. Not a whole lot of claims on it's superior security.

Either way, what are you disagreeing with me with? We had a huge number of discussion here in October when several people's boards were suddenly getting deluged with spam. Several people pointing out ReCAPTCHA's flaws. So I'm not sure if you're disagreeing with that, or disagreeing with my point that security questions are much harder for bots to guess.

Allow me to add this to that recaptcha discussion - I run 4 forums, 2 - vbulletin and 2 - SMF. 3 of the 4 forums were getting slammed everyday with 4, 5, 6 and more spam bots every day. All three forums were using captcha with email verification. Once I set up ReCaptcha, the spam stopped right then. Instead of each forum getting 4, 5 or 6 spam bots a day, in the past month one forum has had 2 spammers sign up.



I disagree with your statement -

ReCAPTCHA has pretty much been nullified by the most recent spam bot programs.

I have seen the side by side effects of ReCaptcha on VBulletin and SMF. And on both forums the program was very effective in stopping spam.

Totally agree. I had 50 spammers sign up per day back at the end of sept/start of oct - installed recapcha and haven't had one since.

It's stopped it on mine too. I'm going by the reports of many other members who have reported it being circumvented.

Just to let you know I run a board with reCAPTCHA, and I've been spammed by Xrummer 5.

I have seen a method to trick it thinking it's failed to register so I will try this method.

I had about 100 spam posts everyday once I switched to 3.8.0. I used the email verification thing, and now I'm just watching the spam users register, and my board statistics go up, but them not being able to post.
