Any way to bypass a global ban?

As topic says, is there ANY way at all to bypass a global ban? except for buying new keys etc.

Play on no-cdkey server.
Only option.

There is no possible way to bypass a global ban other than buy another key.
They're cheap on here anyway around $3

Get whitelisted on a server that has bypassed battleye protection, look around there is some threads here offering it but it's not free. Or just get a new cd key for $2 from the buy/sell/trade section.
