The capchas are only turned on when the server is having trouble staying up, which is pretty rarely. They help because they limit the number of connection attempts one IP can make, and they also limit the number of IPs that can be used to make connection attempts, which are both ways to increase the power of DDOS attacks. They actually help a lot, but we only use them as a last resort because they're annoying.

The captchas are just one layer of protection among many layers.

also, considering that I have written custom web server code, I cant imagine how I would go about establishing 10,000 socket calls per second..

Yeah I agree, they seem to have a botnet at their disposal
