You should be clear that nobody in /r/AskModerators can help you as we are just reddit users like you.

The moderators you mentioned did what they are entitled to do by reddit, so reddit will not intervene.

There are also two sides to every story, especially on reddit.

You may want to consider getting that other side of the story. You absolutely will not agree with it, but understanding how those other people see things could reduce your butthurt.

Nobody cares about Internet drama that they are not involved in.

If you tell this story to someone in person you will quickly begin to feel silly.

The best thing for your long term happiness is to put this story behind you and find something to get into.
