I’m updating the list of commission flippers with 
Plant A Tree
It increasingly appears that Plant A Tree and 
Bluefin Tuna are two identities managed by the same operator. What do you think?
Below is a set of on-chain evidence supporting this hypothesis:
1 - Transfers between Plant A Tree and Bluefin Tuna / 
Sandwich

2 - Transfers from Plant A Tree and Bluefin Tuna to this account:

5 - Transfers from both operators to the same Kraken (user wallet):
This is the clearest evidence so far, since a user wallet is personal by definition.
What legitimate explanation is there for two supposedly independent validators sending funds to the same personal wallet?
6 - Transfers from both operators to the same Binance (user wallet):
The same pattern appears again here, this time involving a Binance user wallet.
Once more, two supposedly independent validators are transferring funds to the same personal account.

At this point, it’s reasonable to ask whether Polkadot should take action against validators operating multiple identities, engaging in systematic commission flipping, and behaving in ways that are clearly detrimental to nominators.
Could mechanisms like Proof of Personhood be part of the solution to finally address this long-standing issue?
Looking forward to the community’s thoughts.
