spam protection / massive ip blacklist

Hi Jose, how are you?
A couple of suggestions. Recently I have a spam user that haver registered in several sites with domains hopto.com, mailer.ygto.com, etc. Is there a way to add those domains/ accounts/ user to a blacklist o spammer list?

and a suggestion for IP blacklisted. It could be nice to collect all blacklisted ips of all the sites in one big Blacklist. Don't know how. Maybe could reside in control center or in a service to share the blacklisted ips with other users.

And could be nice to have an option to block via htaccess. You told me before to add via custom code, but will be nice and more easy if we have an option to dinamically add them to htaccess.

Thanks for your great job!

Hi Jose!
Thanks for your comments.
Yes, I have the spamprotection installed in all my sites, checking name, email and IP. But this guy have registered in several sites using "test" as user, alex(anumber)@hopto.com (or other spammy domain). Since the IP's user is not loged at registration, I can do nothing. Just erase his/her account, waiting for his end boring.
Best!
