So if one gets 3th prestige really fast and is not listed in the Top 100 with at least 250 Rounds won, everyone can see the one has cheated. The same for Salvage, one will need at least 250'000 to buy all Characters and Upgrades, if one has the Chew and has got less than that in overall Salvage, the one has cheated.
Also keep in mind that they will probably patch it with the next Patch, so that everyone can get the last Character (The General) without being forced to Prestige 3 Times, so then its not needed anymore anyway.
