We'll create fresh WordPress site with Buddypress Messages Spam Blocker installed. You have 20 minutes to test the plugin after that site we'll be deleted.
If there is a user (or a bot) that signed up at your site this user can start to send messages to every other user.
I had some negative experiences with this and so I wrote a module that should help to block such a spam.
Buddypress Messages Spam Blocker introduces some restrictions to your users:
Their are also some more restrictions for mass mailings (mails that are sent to “friends” of the contact list are not included in this calculation):
Users with the capability “edit_users” (admins etc.) have no restrictions for outgoing messages
Install, activate, and it will work.
More about me and my plugins
Since the year 1999 I do administration, customizing and programming for several forums, communities and social networks. In the year 2013 I switched from another PHP framework to WordPress.
Because not all plugins I’d like to have exist already I wrote some own plugins and I think I’ll continue to do so.
If you have the scope at forums or social networks my other modules might also be interesting for you. Just take a look at my WordPress Profile to see all my Plugins. Use them and if my work helps you to save time, earn money or just makes you happy feel free to donate – Thanks. The donation link can be found at the right sidebar next to this text.
