Well that sucks. I regularly use a VPN for legitimate purposes because my internet provider refuses to buy enough bandwidth to Netflix servers. There are many times where I'll have a shitty stream, then I turn on a VPN and suddenly I'm getting crystal clear HD video, because my VPN provider has more spare bandwidth capacity between their servers and Netflix servers than my ISP. I don't know why Verizon FIOS lets their connection to Netflix become clogged up but for me sometimes using a VPN is the only reliable way I have around the congestion.
I'd hate to be caught up in a ban for using a VPN legitimately without violating regional restrictions.
