Of course, for most of the attacks discussed here its enough to register
one account.

And the fact that some here seem to run blacklists of servers opens very
easy attack vectors: Just register one account (I can do that manually, no
problem with captcha) on your server and start spamming. Voila, your server
is blacklisted on those servers.
