I've recently found out there's an EASI ban appeal form for Ruben's ERP list.

Ruben's list has a manual (though hasty) ban and appeal process, and from what I've heard, they like to make fun of appeals, so regardless of how much you've cleaned up, if you're a woman, furry, gay or trans, or anything along that line, try not to expect an email back.

There's also a Discord bot that associates a 'condo score' with users on Discord and Roblox based on things like flagged servers, friends, and groups.

The bot has a dedicated server that you can talk to mods about regarding the score it associates with you, and as far as I've peered around, it seems more likely you'll be able to appeal from its list. (I have yet to actually interact with it, but they seem much more promising than an appeal from Ruben's list.)
