You know what? I have to take this back. If Etherscan makes it apparent that two accounts are sending ETH to the same customer exchange address, that's another story. There are some addresses that could only be in the control of an exchange. Since the exchange assigns everybody individual ETH addresses, its possible to determine which addresses belong to the exchange based on the fact that all the proceeds always immediately go to the hot or cold wallet of that exchange.

celested did send ETH to an address which ChuckBuck also sent ETH to -- it is an customer exchange address for Bittrex:



I added in the name labels to Etherscan, but anybody can check the address and previously researched ETH addresses to confirm. You can see that whatever gets sent to this address immediately goes to the "Bittrex 2" wallet address. This means it is the address assigned by Bittrex to ChuckBuck.

ETH transfers that feed into this address also connect these other members:

Little Mouse may have already mentioned it, but this post expands on the connection between some of these.
ChuckBuck and paul gatt were also sending ETH to this same customer exchange address for Binance:



Again, I assigned name labels to the addresses and they are all verifiable based on info mentioned in this thread.

I know for sure its not enough to ban somebody for ban evasion, but there could have been some bounty cheating going on -- I didn't look enough into it. It certainly does look like a huge farm of alts though. After all of this, though, I still don't see a solid connection between CB and SourLemonX.

It's very late for me, and perhaps I'm missing something, so I'm not rushing to any judgments yet. I'd also like to give ChuckBuck and whoever else a chance to respond before saying anything else.
