When support tells me "try to turn of your VPN" they are telling me to compromise my privacy just because they do shitty job in spam protection/whatever.

In case I am a paying customer be sure I won't ne one very quickly.
If website/software does not work, because I have "bad IP" or I have an AdBlock I simply close it and lose interest.
