Too many requests to the site too quickly will land you a temp IP ban. The more it happens in a period the longer the ban gets. Its part of the anti-shill/DDOS/Bot protection that has setup.
I usually have a ton of tabs open and sometimes the browser restarts for a update or crashes. When every single tab (probably like 50) makes a request at the exact same time it's a good way to get on the ban list. x.x
I guess I've never hit the limit. Challenge accepted.
