I help a lot of people too, but I only get negative reactions. It's like they think I'm a bad user. Also I used to hate imgflip mods because I thought they were toxic. They ignore my flags, delete my comments that don't even break the ToS. And when I ask for help, they usually don't help me. I myself know how to moderate. Although I'm not old enough to be a site mod, I know how to do it.
Here are some tips
-Delete comments that will start a fight
-Disapprove upvote begging memes, as they will only get negative feedback
-Look at a user's history. If an image they submitted was reposted in diff streams, then don't feature it.
-Delete comments that stalk other users
-Disapprove discriminatory memes
-If you believe the image is a repost, search the image and if it was somewhere else, then it's a repost.
-Don't immediately ban users. Just give them a warning first.
