Honestly think that this might be one the things that gets more newbies in trouble then anything. You get on a list like steemcleaners and they flag you big time and there are other accounts too. It's a pretty common mistake assuming that if you link to the source you can use photos but they are protected by copyright law.

I always notice these things...can't help myself. When it's a cut/paste article I flag it and those are pretty obvious most of the time as the average person just doesn't write like a professional. Plus so many steemit users are ESL that when they write flawless English with big words that people don't use daily it's a big red flag and it gets checked out.
