- Author: Mickaël Rémond

Following a [recent attack on some visible public XMPP servers](https://mail.jabber.org/pipermail/operators/2009-March/000425.html?ref=process-one.net), we have just released a CAPTCHA support for chat rooms and documented the deployment on ProcessOne Wiki. See [Fighting Multi-User Chat SPAM with CAPTCHA](https://support.process-one.net/doc/display/XAAI/Fighting+Multi-User+Chat+SPAM+with+CAPTCHA?ref=process-one.net).

The deployment process is documented for the newly released ejabberd-2.0.4.

As usual, comments are welcome !
