My spammers all sign up with .info email addresses. Is there any way to just block all .info?
Legitimate members should use normal .com emails, like normal people. 
Sounds like you’ve been caught by the spam filter. One of us moderators will resolve this issue for you soon (I am at work at the moment).
We didn’t ignore your threads, they were caught in Akismet and marked as spam.
@anointed, can you try adding that line into “wp-plugins/bp-custom.php” ?
It should work in wp-config.php or any other file that loads before BuddyPress does. The goal obviously is not to modify a file that’s replaced by core updates, so wp-config.php or bp-custom.php is safer than bp-core.php.
The code…
/* Define on which blog ID BuddyPress should run */
if ( !defined( 'BP_ROOT_BLOG' ) )
define( 'BP_ROOT_BLOG', 1 );
Checks to see if BP_ROOT_BLOG was defined by any other file previous to BuddyPress loading, which is done inside the “plugins_loaded” hook which is in wp-settings.php, which is loaded after wp-config.php.
PM me again if your topics are marked as spam, and I can open them back up.
I’m not sure how Facebook connect works… but allowing sign up or not is simply another configuration setting. I think it’s under the WPMU settings menu.
@Xevo
I think I was not clear. let me explain it. I want to disable regular signup process and enable facebook connect and orher social networks. this way I think people who uses our blog has to be confirmed from another networks.
Thanks you very much David !
I have just changed the settings and it works fine !
@Erich73: Um… just change your WordPress discussion settings in the dashboard.
so how to adjust the settings in a way that “unregistered users” and “not-logged-in users” are not able to post a comment to my main-blog at all ? Only registered and logged-in-users are able to comment ?
Do I need to install a plug-in for this simple feature ?
thanks !
This might help you further.

And why take the social out of a social community plugin..?
Ok then. Jeff, is it OK if I repost my question in the missing linked-to-thread? I don’t want to spam the troubleshooting board without asking. Thanks. 
You sure that is not spam?
Why did you uninstall SI captcha?
SI CAPTCHA Anti-Spam works with WordPress 2.6+, WPMU, and BuddyPress
https://wordpress.org/extend/plugins/si-captcha-for-wordpress/
WP-reCAPTCHA is not up to date for BuddyPress 1.1, that is why it does not work.
Could this be used as a simple captcha? ie 2+2= “4” and they have to put “4”. I have seen simple captchas like this where the field is labeled name or something, so the spammer put zuingling0234. Normal user just puts 4 and is able to proceed. Your thoughts?
Is this a common problem? Can others who are receiving spam please reply?
Remember – you can turn off emails on your notification settings.
I’m struggling with a lot of spam registrations.
– a lot list country entry as random characters “Ot9XLfiFD7WNCu” Is there a way to set Country so it has to be a legit one?
– a lot come from email addresses such as “myspacee.info” “@mysace.info” Is there a way to force email confirmation … so they have to receive an email and click on a link to confirm registration?
– is there a way to mark someone as a spammer and delete them at the same time in the admin?
Sigh… I don’t have time for this so I may give up.
Would be nice if a site user can “Flag” a spam entry to disable the user.
I’m not aware of any captcha plugins for this, but it’s a good idea. I haven’t time to look into the code atm.
Were you able to resolve the problem?
I have a similar plugin that is fully WPMU and BuddyPress compatible:
SI CAPTCHA Anti-Spam
https://wordpress.org/extend/plugins/si-captcha-for-wordpress/
If you use this on Buddypress be sure to update to the latest version of SI CAPTCHA Anti-Spam
https://wordpress.org/extend/plugins/si-captcha-for-wordpress/
== Changelog ==
= 2.0.4 =
– (03 Oct 2009) – Fixed session error on the members and groups pages on Buddypress versions.
I also just noticed that buddypress profiles don’t import from wordpress profiles or vice versa. It takes enough tooth pulling to get people to complete one profile. Adding those fields to sign up would be good because required fields would also have some anti-spam benefits.
I read your example. I need something with a wider net. First off, the robot registration never leave an e-mail address. Unlike WP comment spam, WPMU registration robots appear able to bypass required fields, including e-mail address.
I receive e-mails announcing new registrations that contain only IP addresses. Meaning I would need to include hundreds of IP addresses in your code.
The real solution is somehow create a bullet-proof required registration field or move the registration page behind a firewall. I’ve seen single-user WordPress installations that move the wp-admin or wp-signup pages to avoid robot attacks using the default name and location of these pages.
@ wordpressfan
Did you read this post ?
I give a solution. Not perfect but it works

Askimet does great catching spammers comments on regular WordPress installations, but WordPress MU is commonly the target of spam registrations, which is my problem. I tried reCaptcha and the same day had to delete spammers.
I’m hoping a future version of BuddyPress or WPMU will include finer security, allowing admins to block access to only humanly-registered users, rather than either shut off all registrations. Another possibility would be to follow the example of WordPress and allow admins to relocate or rename the registration component.
I use reCaptcha with askiment in a bundle, well….i will see the result after launch the site
@r-a-y: I added the .htaccess commands to avoid robot registrations. We’ll see how that works.
Just an update, Matt Kern just made a post on the BP forums about his manually-approve signup plugin for WPMU:
