The purpose of the CAPTCHA system is to ensure that spambots are not able to constantly sign up and flood the forum with posts (something it doesn't do [http://www.escapistmagazine.com/forums/read/9.300279-Have-you-ever-bought-a-game-you-knew-nothing-about-and-upon-playing-it-found-it-to-be-AWESOME?page=2#11953089], but that's a discussion for later). Why not disable the requirement after an account has something like a hundred posts, and has presumably proven that it is not a spambot?
Moderation tends to jump on padding posts reasonably quickly, so it's unlikely that they could just spam a hundred posts and then let the bots do the work. The only reason I can think of to not do this is that its not a standard feature in your CAPTCHA plugin, but what are sysadmins for? The forum's power users get to stop typing (more) nonsensical gibberish in every other post, everyone gets to stop seeing disbelieving appendations of whatever phrase the system came up with tied to the end of a post with a bad pun, and I don't have to type "lonvies misaseru" when I'm trying to make a thread complaining about the service on a forum I access for free.
What say you?
