User registration spam is prevalent in BuddyPress.
One way to dramatically decrease signup spam is to restrict the email address domains that users can sign up with.
WordPress multisite has a native option called “Limited Email Registrations”. But this option requires you to enter the full email domain. For example, if you only wanted to allow .edu email addresses to register, this is not possible.
This plugin restricts registrations to the email domains that you specify and works in WordPress single-site and multi-site.
Plugin was developed for the <a href="http://commons.gc.cuny.edu" rel="nofollow ugc">CUNY Academic Commons</a>. Licensed under the GPLv2 or later.

Tested on BuddyPress 2.5, but should work all the way down to BuddyPress 1.6.

Prevent users and bots from accessing the BuddyPress or bbPress areas of your website(s) until they are approved.
This BuddyPress extension allows you to enable user moderation for new members, as well as help create a private network for your users. If moderation is enabled, any new members will be denied access to your BuddyPress and bbPress areas on your site, with the exception of their own user profile. They will be allowed to edit and configure that much. They will also not be listed in the members lists on the frontend until approved. Custom messages are available so you can tailor them to the tone of your website and community. When an admin approves or denies a user, email notifications will be sent to let them know of the decision.
Requires BuddyPress version 1.7 or higher and bbPress 2.0 or higher.
<h3>General Data Protection Regulation</h3>
BuddyPress Registration Options temporarily stores user IP addresses as user meta to help validate and vet pending users. Saved IP values are deleted upon both approval and denial of pending user. No other personal data is recorded.
