We get sporadic, but increasing bot activity. Right now we see a lot more of it in the registration section and the contact forms, so we're taking some preemptive action. The problem is that once a bot knows how to post on the forums, the controller can set it to do it whenever, and however much, they want. Like, for example, on a holiday or weekend when there's a lot fewer moderators and staff around.Boneasse said:There were a couple of threads yesterday, started by a bot. I think it's fine this way, as long as the website registers the IP/Cookies of our browsers we only have to type in the Captcha once per day. So it's no biggie. Whatever keeps the site clean.
Unfortunately, I can't just do it once per day, because a bot owner could do the captcha once manually and then let loose the bot right after. Most spammers wouldn't, but I can't discount the more malicious asshats out there (that may instead be posting shock porn, for example). So there are spot checks to limit how much damage an individual bot could do.
Technically, having a captcha on every post would be the "best" solution, but that's way too annoying. Hopefully what I've put in is a good balance between the two.
