Spamm attack!!! https://www.s4f.net

Hi @ibruq ,

You can use “Comment Blacklist” WordPress feature.
It can be found in admin area: Settings => Discussion.
/wp-admin/options-discussion.php

Try to add “s4f.net” into that textarea and see if that will solve your issue.

Thank you, I already did that, and also closed old comments to avoid server overload.

After many years of no spam, it seems that they found a way to sneak into plugin defense.

No, I don’t think this is the case.
But even if what you are saying is true and other users will have similar complain, I will change the blocking algorithm slightly (what I actually do from time to time) and spammers have to adapt for new changes.
