You can find the moderators for each community in that community’s sidebar - just head to their profile and message them. This would be the process for both questions about community-specific rules, and appeals of moderator actions.
Thanks!
The downside to this solution is that the message is only guaranteed to be seen by the moderator you messaged, rather than the entire mod team, but we can and do communicate with each other as needed.
