Chances are, knowing the situation, the that convo was one-way (he probably never answered) and that the sender was banned afterwards (was spamming our PM system).
Can someone point me to, or carefully explain, what happens in all situations regarding conversations? That is, stuff like:
1. What happens to one way convos of a banned member?
2. What happens when someone leaves a convo - a one way or a two way?
and all the other possible moves?
I can state, without question, that no one deleted any of his convos.
