Could forum.dlang.org remember how many captchas I filled out?

Akismet thinks your post looks like spam. Please solve a 
CAPTCHA to continue.

I've filled out one of these for every post I've made here. Yet 
I'm logged in, with a persistent state on the server side. Could 
something be implemented along the lines of:

ALTER TABLE users ADD COLUMN num_captchas_solved INTEGER DEFAULT 
0 NOT NULL ETC;

I can understand if even an ordinary user like myself could be 
suspected of spam. The Internet doesn't make it easy to 
distinguish in a lot of cases. But my account login status does. 
If you made it so someone solving 12 captchas didn't get asked 
any more (until they actually start sending spam), that'd be 
really nice.

You could even award achievements! (Achievement unlocked: On 
Fire. 100 posts in a week? Jeezus!)

Not sure if this is the right place to ask, but this is regarding 
the posting server on forums.dlang.org, which I use to access all 
these mailing lists and such, without getting all the messages in 
all the lists sent to my email inbox.
