My basic point is that Akismet would never have allowed those airline spammers everyone is getting hit by to post anything, even right out of the gate on a fresh account. The current system in IPS appears to be almost entirely defensive/reactive in nature and has proven wholly ineffective at handling the problem.
Even when setting up hCaptcha at "difficult" level, the problem remains. The only other advice I've seen you guys or anyone else give is to pay $20 for the CleanTalk app. While I'm sure that's an effective solution, it's one that raises the expense of running the package as a whole and not all of us want to do that.
If there's something more you guy have to suggest on the subject, I'm sure we'd all appreciate knowing.
I've been using Akismet for years on non-standard packages it wasn't even meant to be used on, and it's proven solid and reliable. Spammers have yet to succeed in bypassing it for posting, and only occasionally get past it for initial account registration.
