I’ve been having the same problem even on my home IP. It only happens when I’m using Firefox though. If I use Chrome, and oddly enough change my IP by routing through my rented VPS and pass a few captchas then Google will eventually start to trust Firefox from my home IP. It’s bizarre and Google is really starting to piss me off because I’m wasting so much time on this shit.

Nothing, it’s just an extra charge so that the company can make more money.
