I'm sure that one could feed your posts to one of those newfangled AI/ML thingies and produce somewhat coherent LoyceV-like posts for at least two days.

As for Simwhatshername (can't be bothered to remember how many Ms and Ys there are, sorry), the current owner of the account is such a clown that regardless of whether it's the same person as the original owner or not, there is very little reason to trust them with anything. But I find OP's observations quite interesting and credible, and considering the password change I'd say ownership change is likely to have happened.
