Does BuddyPress affect "Banned Email Domains"?

Hi,

We are running WP3.0 stable, BP1.2.4.

I've added domains to the "Banned Email Domains" but the domains are not blocked.

I saw this issue raised in this thread:
terry hall:Bravo... Except for the buddypress not referencing the list.

djsteve: I've created quite the list[of banned domains], and would maybe have some to add to it.. but then I found that buddypress skips the list entirely, and gave up on it..

Any suggestions to solve this without using Anti-splog?

Thanks.
