I typically make my own memes, or take selfies. I rarely post serious content here, I treat Steem like Facebook. If I do more "important" content then the community reacts positively and I get more engagement (and STEEM). Not to mention, I've been focusing mostly on growing Steem Power, not necessarily caring to grow my personal income, but Steem Power is nice to support serious posters.

I dont support plagiarism, so I don't do it (of course), and I'm with you there about not caring so much about IP rules. So hope my content isn't considered spam in yours or other people's eyes. :)
