What version of Nuke are you using?

Are you sure they are not getting in through a hole elsewhere?

Nuke 7.9
bbtonuke 2.0.21

And in bbtonuke you can only post messages if you are a reigstred member and how can they register itself?

Unfortunately versions of Nuke after 7.6 are known to contain security holes, which is why RavenNuke is taken from 7.6 as a base and then built upon to make it even more secure.

A number of questions need answering.

Are you running the latest patched files
Are you using Sentinel?
What additional modules, blocks, hacks are you running?

Also check your logs to see if you can find out how they are bypassing the captcha. It is possible to get through the captcha with the right tools, which is why RN uses a new and improved version.

I good way stop bots from getting through is to add an additional registration field. The bots are simply plugging in the information into the fields it expects, if you add in an additional field, it should trip them up, because it won't be expecting it. As you are you CNB that should be easy, but I suspect they may be bypassing this process all together.

Disable the Forums registration. That's probably where all your bots are going.
(There is a simple code hack hehe)

"How can i see how the bots are bypassing the captcha?"

If your Forums permissions (the permissions on each Forum) are set to allow anonymous posting, then these "bots" are posting this spam without any need for being a registered user.

"My member can only register with Your account"

This is how it should be due to how phpBB forums were integrated in with PHP-Nuke.

"In my bbtonuke forum there is no option to disable the registration via board"

What jakec and evaders is talking about are your forum permissions. If you change them so that only registered users can post, it will cut out most of these spam issues.

However, unfortunately, the spammers are getting more and more sophisticated and even the core PHP-Nuke captcha may not stop them. However, so far, the captcha that is in RavenNuke 2.10.x has not yet been by-passed.

i check all subforum topics and there is always set that only registered members are allowed to do posts.

In some phpBB forum you can only post a URL or image only if you more than 2 day a member and have more than 2 posts. This addon i will need for my site too, but there is nothing like that.

Beneed all these tips you could also try out Trubar (for Nuke) or Trubar silent (don´t know if its already ported to PHP Nuke) wich is an anti-spam-tool a catcha for your forum from

Make sure your forums are up to date. There were some important fixes in the last two versions to plug many of these holes

viper Spammers use often proxies.Is your Proxy blocker activated ? Beneed this the string blocker is very agressive you can add there many words like "phentermine" etc. and also e-mail-addresses like @mail.ru etc.
But you have somewhere a hole.
