They are if it's not actually violating sub rules.

Admins only review mod comments, so if you report a mod it goes to the admins to be reviewed and I was told that they're very bad happy against the mods cuz they don't like when mods are being happy so you should always report the mods that unrightfully banned you, if they leave you a comment, if they don't leave you a comment there's nothing you can do. Now you won't be unbanned but at least they'll get a ban too.

Not true, they're as ban happy as mods

I was banned on my ten year old account for hate speech by saying that j*ws run the media.

Click the 3 little dots next to the mods comment and report them. They have to be reviewed by Reddit admins and they hate overly ban happy mods and will ban the mod, you won't be unbanned but at least some revenge.
