Google reviews, what about to make new account?

Hello,
I need to make a lot of reviews to one google place. I was wondering, if I would do a new gmail account, stop 2 days, later start to make 1 reviews.. I'll get ban or something? Is it safe?

of course 1 proxy = 1 account, private browser, no cookie and that's all.

All good as you mentioned.
Just don't use more than 2 kw in the reviews part.
