definitely not boosting, there are too many points as you can see.

could be modding or glitch?

100% mod/hack now give over??

1.3bill to be persice

Yeah I saw this on the Search&Destroy leader boards I think it's just because SnD gives you 500 or 1000 points a kill so it could be possible.

Impossible, in 9 hours, you can not do 7th prestig ...
