I have just released a new plugin named Scrim Email Saver v0.1 for bbPress! The plugin basically filters your bbPress forum’s posts for email IDs posted by your users and converts them into scrim links so that they are not picked up by bots and your users receive less spam (if not none).
What is Scr.im?
Scrim is a service made by Ozh. To scrim is to protect your email address before sharing it so that only real people will use it. You can read more about scrim on its about page.
