Is there some setting somewhere that can block these or a way to link these accounts to SpamAssassin that can stop this?

You can turn off bounce_unrecognized_goes_to_list_owner. Then you have the problem that a list member may be bouncing with an unrecognized DSN, and you won't know it, but in my experience, this is rare. YMMV

It is better to block these with SpamAssassin in the MTA before they ever get to Mailman, but you could create your own process which would filter the mail and then pipe it to Mailman's mail wrapper with the appropriate arguments, and arrange for the MTA to pipe the -bounces mail to your process instead of directly to the mail wrapper.
