A workstand is really worth it, second hand they can be cheap. Otherwise you can hang it from the seatpost with some rope, not ideal but can allow some work to be done. A new cassette will make it ride much smoother.

Fat bike? Good on you for riding year round.

Might want to change the cassette if you get a chance, but nice to see a good bike getting a new life.

The account has disappeared unsurprisingly.
