That's what I'm trying to test. Last time I've got 800 mostly meaningless comments.
The idea is to stop numerous zergs: you can't ban them one by one, but a little bump on their way can do the job.
To avoid annoying more serious commenters, the captcha should be as simple as it can be. So asking to add 321+625 would be too much, while a question like 2+4 doesn't need any thinking, so I chose two-digit numbers.
This is a small social experiment. I don't know how it'll go.
