I would also like to add, lemmygrad is very different in culture from reddit. There are very few liberals and chuds wandering in because most of their instances have pre-emptively defederated from us. You may still see them on lemmy.ml (sort of the hub instance) but if their instances are not federating they won't see your comments.
We also moderate differently from reddit and because this is such a tight space you'll see a lot of the same usernames all over, including the admins. We purposely keep the rules on the instance simple so that there's not a whole bunch of stuff to remember and due to the aforementioned tight space, we usually act on community reports as sort of sitewide moderation. Don't hesitate to make reports if you see something off, and please give us as much info as you can in the report so we can make a decision.
