Don't hate me for these questions

Ok, so I'm new to this sub.... I like it a lot. But I have a couple questions.

1. Why do so many people obscure their face?
2. Why do you all handle the fish the way you do? It's unhealthy for the fish to handle them like that for pictures. I hope you don't hate too much. This sub is great.
   Please don't handle the fish line that for pictures..
