So, opened up google keyword tool to have a look at some keywords to be forwarded to their sign up page when clicking 'search' went back, tried again then this page popped up? We're sorry... ... but your computer or network may be sending automated queries. To protect our users, we can't process your request right now. Has this happened to anyone before? I don't use any software for keyword research, just have a random gander now and again on the google keyword tool. No idea..
