I agree not to be soft on abusers. If a mustake is make apologize and ubless they are unreasonable, they should be able to get past it.
I think the only people who have a hard time coming back are those who rage quit, screw up, or only blog about dodgy investments and promotions. Steem has its fair share, but a lot of the famous examples have been pushed out.
I agree fake art is a huge problem. Whenever ai take a photo and its not mine I explain it. If it is artwork I'm photographing that is especially mimportant. It's like doing a book report without mentioning the author, except more misleading unless the lainting is very famous.
