[Mailman-Users] Hackers subscribing lots of people

Hello,

We're running mailman 2.

Quite a few script kiddies and other idiots have figured out that they can use our mailman installation to annoy people. They bypass the subscribe page directly, and run cgi-bin/subscribe directly - many, many times.

We fixed the problem by removing the appropriate executable permission from cgi-bin/subscribe and rewriting the list info page to handle subscriptions differently. (We removed the Subscribe fields and button.)

While this works, it's inelegant and a bit convoluted.

Is there another way to prevent this, and leave the default info page intact?

Thanks.
