That may explain why they're not adding new slots: Now as Bitcoin's price rose again, campaign participants are posting more - and so the campaign budget rises, even in BTC.
It happens in most of campaigns, that pay per post, not only in ChipMixer. There is a significant dips of both postcounts and btc-paid in January of 2019, when bitcoin stood at its bottom range.
Because theymos stepped in, I don't think bill gator will be tagged red for too long. He deserves more, not only because he contributed good things and have big net-effects in the forum; but aslo in the way theymos claimed that notable users whom started from bought accounts have chance to be recognised in the forum. Even theymos has never forced DT members leave or remove feedbacks on any case, such post of theymos might have good positive impacts on bill gator's current negative feedback.
One interesting question pops up: Will bill gator be able to take his slot in Chip Mixer back?

This is part of why account trading is strongly discouraged. Usually we won't even consider this excuse, since only admins can properly investigate it, it takes too much time, it's often too ambiguous, and you really shouldn't be trading accounts anyway. But especially for very veteran members, we do occasionally look into these claims and reconsider the matter based on them. This isn't the first case like this: there are a surprising number of notable members who originally bought their accounts.
After looking at the logs, I find it likely that this story is true, so it wasn't him personally who did the plagiarism. Trading accounts is strongly discouraged, but not against the rules. Therefore, the ban is removed.
This action may be controversial, and now I'll probably have everyone appealing based on "I bought the account from my neighbor!" (Which I'll nearly always reject...) But even though it is largely bill gator's fault, I just find it on the whole too unfair to treat him as though he did something when I'm looking at evidence showing that he didn't.
