We actively block VPNs that are detected. I can bet you that someone was doing something they shouldn't have been to get the IP blocked. (There are three levels of blocks happening, some are soft blocks and others are hard blocks where it's just a flat packet drop.)
There's really no reason to use a VPN here unless you're trying to mask yourself from whomever's watching you locally. All it does for us is trigger suspicion and skew the site stats. (So many romanians here for some reason. )
Those cheap/free VPN's are usually hosted from Romania where there is no oversight there.
Thus, people using those services look like they are in Romania 'cause that's where the service endpoint is.
