I have never heard of this. I use a vpn for unlocking sites I want to visit like Netflix esspecially. I also do it to keep my privacy. I have never ever had a problem with my VPN by any website or game. I have never been told my ip looks suspicious either. What VPN are you using ? Try use a better one maybe.
Any popular VPN is gonna run into trouble when browsing sites who IP ban.
It's more luck at this point trying to use one that wasn't abused in the past, not much to do with the quality of the VPN.
If you're using a public provider, there's not much you can do.
