i’ve used SI CAPTCHA Anti-Spam on a single install without issue, never tested with multisite though.

@rickkumar – I noticed loginradius have been spamming the Internet with fake users / testimonials for their product — so probably good to avoid that one.

If you are looking for another free solution – you can investigate HybridAuth.  That one’s a PHP library, rather than a plugin, so you’d have to do some coding, but on the positive side would gain a lot more flexibility.

Yes, they violate guideline 10.

It’s a shame the guidelines don’t also include ‘spam / misleading marketing’

The best solution I have found to stop spam is forcing users to fill out a CAPTCHA on registration. It’s not ideal, but it’s part of the price of entry for our community.

another plug in that might help you is called ban hammer it allows you to blacklist specific emails or entire domains

@Gregykos believe it or not a lot of those “robots” are actually people.

Im surprised the buddypress team did not come with a permanent solution about this major problem ….
What major problem and why or how could BP sort it if – no offence to BP – more mature apps can’t! If a numpty idiot is paid to post pointless irritating spam on as many sites as they can in day then what can you do other than as suggested manually approve, what would you wish to do? Or are we talking about some other issue?

Ok, I knew this is not a good option.
This is not a buddypress only problem, it’s global. Even the best platforms around the world suffers from spammers!

I just forgot to say that, to enable auto activation of users, this plugin is needed: “BP Disable Activation” (just for others who might like that)

@themightymo I have tried that plugin with out any results. I helps for human but not for spambots that register everyday ..

If you run a small community, and you are able to confirm registrations, you can use the plugin “Confirm User Registration”. by this plugin, users register to your website will be activated automatically, but they cannot post anything untill you confirm their registration. If you guess the registered user might be a spammer, you can delete it before it can harm your website. Most of the time a spammer uses irregullar email addresse, or username.
Although this is not a sollution, but it can help you prevent spammers do what they want.

Spammers register on every single forum or community/blog on the net how do envisage stopping them? It’s simply a pandemic that has to be manually dealt with, there can’t be automated / plugin solutions for everything.

marking as a spammer won’t delete the account it only puts it in limbo. Why not just delete them from your dashboard. There may be some plugin to help with this but most likely it has not been updated in ages to I can’t validate their usefulness.

@aaclayton – It sounds like you have/had a plugin or theme conflict of some sort, as SI Captcha should work out of the box. Good to hear you found a plugin that works.
