While mailman does double opt-in, one can still fill a mailbox with account
confirmations, what are the methods to stop a bot submitting email addresses
for registration across several lists?
Mailman 3 will not pend a registration request more than once for an
email/mailing list combination.  It's possible to spam every list at least
once though, and I'm not sure what you could do about that.
May be a captcha? Or some more modern techniques...
