They all got caught via quick typing or TL0-moderate-threads.
I wish we didn’t have to use TL0-moderate tho, I know from personal experience what a pain it is joining a forum then posting a thread which you want a quick answer to but it goes into moderate… sometimes for days. Hopefully that won’t happen as we have quite a few mods onboard.
I read that you hate spam, thank you for making DC unfriendly to spammers 
That’s good to know. When we first got hit by a huge spam attack (several years ago) we resorted to simply banning several of the worst culprits by country - on a server level. Not ideal but was very effective.
I’m going to have to look into it. I vaguely remembering trying it (on my blog I think) and found that it didn’t really do much, but that was a long time ago.
When it’s installed on DC do we get some sort of notifications (in the logs) of how many posts/threads Akismet is catching? Also, is it given precedence so that we can use the block by fast typing and put tl0 users threads in moderation as fail-safes? This would also help determine whether it’s worth keeping.
The only other drawback (which isn’t too big a deal for the programming forums) is posts being sent to akismet (on some of the forums I run some posts can be of a highly personal nature).
