Mass cheating Sucks anyways....and most of people now know where its happening so rather focusing on how can we hide the mass cheating source we should come upto any permanent solutions for this...

1.Some thing like copyright claim on there groups

2.Cf servers may strictly check the codes that took equal spaces and equal time (like to catch someone changed only variable names),

3.However they are not the permanent solutions, I request you all to put some solutions in the comments ,so that These cheaters may be caught and and suspended.
