I honestly don't see how you think that everyone insulted that skinner, they were giving him praise, and no it was not fake praise. Multiple people were glad to see a skin like that get onto popreel because it was a refresher from the wall or teenage girl skins.
They were not insulting him.
I can tell you I was glad that he deserved it, you can obviously see he was trying in the comments. He tried on that skin even if it isn't shaded. Everyone goes through a stage like that so saying something like 'horrible' is not going to help him improve. It's rude and shouldn't be allowed.
