Socrates has a meme stream that gives folks an idea what to do. I've been online for a few decades, so there's not much there I haven't experienced.
I'm not an expert, But am knowledgeable. Eventually, I'll put a meme stream together on ways to earn points. Right now I'm helping ghostofchurch with his theme week stream.
Getting back to the FAQ, the best that imgflip has offered up is in the ABOUT section and the terms of services. Most are common sense, but it never hurts. The rest, don't be afraid to ask. Most of us know our way around to some extent. My first popular, hot page meme was a statement not begging for points, but trying to figure out how I had gotten so many in just a few days. Positive confusion, LOL. You're definitely on the right track. Those that aren't don't like me because I do a fair critique of their posts.
Only other advice I can give: don't be afraid to upvote and comment on other people's posts that you like. It helps you get better known, and flippers like dealing with positive people. Also, keep comments positive. I'm able to do negative reviews because I have a rep of being fair. And negative reviews consist of the ability to analyze what they have, advise how to change it, and work with them. Most don't want to, but they are usually the most immature members here. Not all of them are kids.
