Can we considering move the contest time to sometimes when Indians couldn't participate? Like almost half (or even more) of the indian accounts ever do is waiting for paid solutions to get out and cheat during contests.
This will also allow the US participants to participate. The start time in the US east coast is 9:30am and 6:30 am in the US west coast. The contests will have a lot more high quality participants rather than just a bunch of Indian cheaters.
We can keep most of the contests schedule to current time, but once or twice a month, we could have a contest during 12am to 6am India time so that a lot more US participants can do contests, and free (almost) of Indian cheaters
If your deductive reasoning is on the level of (most cheaters are Indian) $$$\implies$$$ (most Indians are cheaters) then in no way are you fit to do competitive programming.
