That feeling after is horrible

Spent alot of time making a custom for this fan, I put effort into it and I sent it to him. He loved it. I had a feeling it was odd bcs when I sent him the first custom he immediately asked for another one after . Anyways, I just seen today that he got his money back for it. It’s happened to me a few times but I just feel so disgusting and a bit scared and it honestly makes me want to not do OF anymore. For me it’s just the feeling of why did they do that ….to sell the video or is it for their own personal use? It’s just so confusing and such a violation and his account is still there and hasn’t been deleted by only fans… his name is @u19960974
