I need some advice from some of more experienced users who deal on a regular basis with spammers.
Personally, I think XF 1.2 has amazing improvements. So far, I did the following things:
1) Stop Forum Spam: Reject registrations when 1 warning flag is detected
2) Enabled DNSBL honeypot API key and blocked the registration
3) Enabled Akismet
Thank you for letting me know what other steps I should take and if you think is appropriate the 1 warning flag for SFS. I would also like to know if there is a way to automatically mark a properly registered user as spammer and report it. You can spot easy those users, they have weird nicknames and email addresses (i.e. GiuseppeMqrf email@example.com).
