Безопасен ли webmetrics.com?

I hate them! Signed up for trial. and immediately noticed hundreds in traffic to site. Problem though all of them are zero second visits from every single corner of this planet, which leads to close to 100% of bounce rate, which basically is a knife to new site's rankings, which is basically bad for business. It took me 12 hours to pin down problem to webmetrics and only after digging in apache usage logs. I'm sure requests are ok, but other providers do simple "GET / HTTP/1.0" 200 63759 "-", which are not registered as human visit (like pingdom does). Webmetrics load full page! And I'm not even talking about bandwidth usage!
