Sadly, I believe there could've been a better approach to what happened to your BF. Especially since he seems to be a legit user, and as he claimed and proved, the post was original.
I think this situation could've been resolved better if there had been proper communication.
Yes, it's true. He decided to write that post to raise awareness of the situation, and not simply let the bad experience be forgotten without learning anything. However it doesn't matter, we keep going on 😊🙌
