Contrary to what is usually believed, there are no GRE requirements. Decent universities do not use a strict cutoff to shortlist students based on their GRE scores. They know that the GRE might not be a good indicator of the students' performance, for this reason, many departments have started shunning the GRE requirements. Also, the admission committee recognizes that non-English speakers do have problems in the verbal portion of the test, and they weigh them accordingly.

So, no, even if people cheat in the GRE, this does not affect you.
