Yes Kyle, I can see how that would be a big problem. I think the best solution would be this: If, when I created/signed up for my team online back in January, I was accepted by the computer as a 3.0 (especially if I'm a computer-rated 3.0, which I am), then that should be what I remain until the season ends in April, regardless of how well I may do. There should not be any way I can get bumped up/DQed in the middle of the season, even if I win all my matches 6-0, 6-0 (which, believe me, ain't gonna happen, not the way I play!). This would eliminate any need, perceived or otherwise, to tank in a match. Unfortunately, as I've stated several times already, that's not how it's done. Theoretically, I could get bumped up/DQed 2/3 of the way through the season, retroactively forfeiting all my matches, thereby hurting my team's chances of going to the state championships. So unfortunately, in order to avoid any potential DQs, we're going to have to plan on some of my players tanking a match. I don't like it, my players don't like it (hell, who WANTS to lose a match?!), but that's the reality we face...
You are in a tough position. Don't throw matches and possibly get DQ'd. Do throw matches and possibly get sanctioned and banned. I'd go with the one that when you explain it, sounds ethical.
