Maybe Emma and Robert are identical twins, so they dress and look the same.
I have zero experience with blockchain analysis, but unless I am wrong, there was only one transaction that was carried out from 1-13 July 2022 involving an output of 28 bitcoins. That one was sent on 8 July. That (obviously not fake) review (at all) doesn't mention the time when the transaction supposedly happened. I would like to see that signed message as well, or better yet an excuse why OP can't do it.
