If you're doing it on your main, i don't think you need proxy since it'd look more legit using your actual ip and location. Switching computers shouldn't matter. I play on my mac mostly also and cheat on the pc lol To be extra safe do all your score sending cheating before the 10th of the month. After that the scores get too high and more likely to get into review territory. (Reviewed scores aren't necessarily bad, as the program makes it look like a real user but still just to be safe. I've had multiple reviews gone through without issues.)
