Would I get banned here for being over active? I got banned from reddit because they thought I was a bot. And don't want to repeat the same mistake here. Thank you ahead of time.

All of the moderation here is done by actual human beings who are (mostly) reasonable. If they make a mistake, you can just message them, and they'll fix it. No one is banned by an algorithm.

In reality, you can't actually be banned from lemmy, because it's a federated platform. You can only be banned from an instance.
