You need some antigrav cats. Nothing can stop them. Nothing.
I haven't seen a big improvement. I've seen some improvement, but not a whole lot. Some spamming is down, but many of the same spammers are here. Fuckery is down somewhat but "chat" was really an issue. Some comraderie is good for morale. I wouldn't the captcha if I could just do one but the last post took 5 fucking times and I know I got it right at least three times.
