hOW dO YOU pOWERLEVEL???

The acronym MPGH is censored by Nexon for a reason... they know people from it hack, and why would you make both the title AND the pw MPGH? that's just screaming I'm in affiliation with MPGH, investigate me please.
Also, Nexon monitors your exp and gp gain (at least, I think).

if u get too much points in Quantine u get no exp

That too. What is it, over 200 points you get NO exp?

Do some Spyhunts, get people that will listen to you.

Put the game for 16mins and just kill with intel until the 2 minute mark. Then get SS. Take turns on switiching off on SS so you all rank up.
