The forum is under essentially constant attack from the spammers you describe, each one that gets through the automated anti spam system is manually dealt with…
Wow, as I don’t recall more than 1 or 2 spam emails in as many years, that must be a lot of very intensive forum monitoring you guys are doing to be so successful in nabbing the rare one that sneaks through the filters!
I remember a lot of attacks. One of them posted zillions of messages for online bets and jewellery sales.
Yep me too. I expect moderators can delete a user and all his posts in 1 go though, so that should be fairly quick to clean up.
Those spammers are actual humans who, I imagine, get pennies per post they can make, so anti-spam measures in software don’t stop them. Posts are made from the same countries where they make cheap clothes. I think I would rather be spamming forums than working in a clothing factory, if I was in one of those countries.
The solution put in place after the big spam attacks in 2014 is pretty low tech actually - new members have to wait for manual approval of their first post. Slows things down for that first post, but makes for a spamless forum.
