People may assume that you cheat for as long as they want. Overriding their opinions is pretty much beyond our reach. I've also been accused of cheating quite a lot, from newbies to regular players alike, but I've always managed to prove them wrong.
The easiest and least painful solution to this would be trying what I did. As I said, you have nothing to lose if more than one admin watches a round with you (given you do not cheat). If you do, however, prefer to let emotions invade your thoughts on things like here, then that's going to continue to be a bad ride here and be a bad ride elsewhere, in general.
