Thats what happens if you don't know what your doing.
Ps: That server had an issue with rank which only showed you as 200 but still levels up as usual. I've learned it the hard way too but thankfully I haven't done any of these DNS madness on my main account.
At least nobody is rank 1 with -20689009814 I have to rank up just to level up to 2
The sooner Sony and R* start working together and console banning people using DNS servers the better. It's getting way too out of hand now. At first it wasn't as bad, no almost every lobby I join its some wannabe hacker on a DNS server.
