Using Google as free proxy

Ever since everyone (maybe not everyone but at least most people) know about Google Translate tool can be used as a proxy to browse various site … i don't think stats tracking can give you an accurate statistic to determine where your visitors located so you can create targetted content specifically for your site visitor .. and here’s the user agent from the translation tool by google …

Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1) ,gzip(gfe) (via translate.google.com)
The user agent may vary depend on the visitor browser but they always leave via translate.google.com behind the real user agent

I’m just wondering why does everyone think it's cool to use Google as a proxy ? why they don't just browse the internet like normal people do ? Well .. if it's a protected site .. maybe it can be useful for you, but to browse normal site ? well .. if it's for me i dont think it's necessary because there are various reason for it .. except when used on filesharing site :D
