HideMyAss VPN for Analytics / Webmaster tools

Has anyone used HideMyAss VPN for hiding from Google?

I've got 50+ website network and I'd like to install analytics and webmaster tools on it.
I don't want to login into analytics with my IP 50-times.
I also don't want to buy 50 different proxies.
HMA VPN offers different VPN servers and IPs so I thought it would be the perfect solution.

Will I get my sites banned doing this or am I safe?

It'll work but, you're really going to login to 50 different accounts all the time???

Why not use 50 websites in one account?

@the_demon: not all the time, one in a while.
@--sKy--: because I don't want Google to know all those sites are mine.
