Not quite. ReCaptcha has been cracked, and so has the old phpBB one. The not have also got pretty good at Q&A CAPTCHA, but I would still recommend using it (but with difficult, unique questions)felguard wrote:Try using a captcha!

Well said - although some bots seem to be catching up and can now parse the question. Example: "What colour is the sky" no longer stops them.Jim_UK wrote:Make your registration page unique by adding an instruction to type in a given word or phrase. You can actually show it on the page as the bots can not read. That keeps out all the bots.
If they get through that then they are human that are registering.
Make them click an email link to complete registration. That keeps out humans that do not have genuine email addys.
If they still get in they are human and have a genuine email address. Now it is down to yourself and moderators to curtail their activities as quickly as possible. Do not start by deleting posts as you will likely not keep pace with their posting. Start by deactivating their account and then delete posts.
There is little point in doing anything beyond that as an IP ban will not work with a dynamic IP user. Banning email addresses and user names is pointless as they just create another.
Vigilance of your team is key here. Plus ask users to report any spam straight away to anyone on the team.
In 7 years I have only had about half a dozen spammers - all human and all blocked and nuked within less than an hour.
Spammers are only a big problem if you let them be. Be proactive.

No bot has ever got through that in 7 years.
