Lots of spam getting through

We’ve been fighting a spammer for the past several months and Akismet has not stopped any of his posts. They’ve moved to post URLs like “hdate.online <<<< Check my profile” as their friendly name in their profile and then say “click my profile” or “check my profile” to drive people to their sites. They have used over 50 different domains which we end up manually blocking – they come from different IPs and emails. They even added hidden dashes in the text which we’ve stripped out to help the process. But no matter how much we mark these as spam, they keep coming. Have you seen this spam on other sites?

some patterns we’ve seen:
