Sounds like a good system to me. I mean it's probably either this or bans in most cases. And I've always said, trying to control it instead of banning it is 100% better since you can keep your eyes on where it actually is, unlike when its trying to hide because of the ban. This also might dissuade gamblers from actually gambling? Might is the keyword though. I'd like them to add a few say minimum requirements to it I guess? For example, only after a certain amount is wagered or a specific bet won exceeds a set amount. Maybe even tally in losses as part of it?

As for what a gambler would think about it, well anything that gets a cut from their winnings definitely doesn't look fair.
