Okay, so first of all, let's be clear:
tartaric didn't cheat: he happens to be a super nice guy—an altruist, even—who kindly gave some of his time to help poor little Leela to play on FGS because, you know, without him she wouldn't be able to do that and would live a very boring life indeed

Second, they created a 10 dan rank on FGS I believe, because Fine Art—which happens to be a bot too, probably also using a human collaborator/traitor/cheater to be able to play there

—was already at least a stone stronger than pros... but so what? most pros are still 9 dan on FGS, and now that there is a new rank available, some top human pros (like Ke Jie for instance) could prove themselves to be of a higher caliber than the rest of their peers.
And if tomorrow new bots appear that are even stronger, well, instead of deciding that only the Top God of Bots should be 10 dan and that we should drop everyone else's rank as a consequence, we could just add an 11 dan rank, and a 12 dan one, etc. Sure, humans probably wouldn't be able to reach said ranks, but who cares? It's not like they were able to either without bots around—apart from some genius weirdos, maybe, like Dosaku and who knows who

.
Anyway, sure: if someone creates an account to play with his bot, then the account's strength will be the bot's one, not the human's one. I agree with that, but... so what?
We're not talking about a tournament where someone could win money or whatever... we're not talking about someone playing at an undervalued rank on purpose either, since after creating a new account strong players (humans or bots alike) have no other choice but to climb their way up from a certain rank (3dan?) before reaching their legitimate one (unless they're pros who want to declare themselves as such, in which case they will be granted the (p) or 9dan rank directly, though they won't always do that—far from it).
But in the end, chill out!

Once the bot stabilized at its true rank, then
ALL IS WELL WITH THE WORLD
