vBulletin 3.8 - worst for spam.
 

I have been inundated with spammers since uploading vBulletin 3.8 and it's disappointing there's no tools to combat it. I have yet to find a mod to prevent it either. Any tips?

I had this issue when I updated aswell, and I tried 99% of the things that people told me to do.
In the end I Just went back to 3.7

try either question and answer or recapcha in human verification options. I use recapcha and get no spam whatsoever.

That said, I'm still on 3.7

Interesting. VB3.8.0 has more tools than ever before to help and you state you have no tools? How can that be?

Why would upgrading to 3.8 have anything to do with having more spammers? Aside from the fact that there are more spam prevention tools in 3.8, the methods for preventing spam are the same as before. There's no special vulnerability that's being exploited in 3.8 that isn't in 3.7. Either they're being stopped at registration or they're not.

I haven't had one single spammer & I'm using 3.8 so I doubt it's the software.

Maybe I'm just blind but in that list it all seems to be features from previous versions and nothing new to combat it. I have tried human verification and reCaptcha to no luck.

Have you tried "NoSpam!"? It seems to have all but solved the problem for mass bot registration.

I have. I've logged on this morning and found two or three posting all over the place with links. Might add some more questions, perhaps there's not enough.

Make sure your questions are not math questions or questions that say "type the word [word] in the box" or "are you a human?". Come up with simple, but impossible for bots to guess questions.

You can use HTML with no spam, so I use small images and ask brain dead questions about them. Like "(Fill in the blank) This is a picture of Super___." and then have a picture of Superman, or "What kind of animal is this?" and then have a picture of a dog. Just make sure you don't name the picture anything remotely close to what the answer is.

Also remember that humans can register bots and then send them o'spammin', or bots could have registered months ago and don't start spamming until after you've installed precautions.
