1. what should be reported: nothing.. the report button doesn't work yet. when it does, i guess just report stuff you want an admin to see.
2. what is verification: literaly just a checkmark.. no functional purpose.
3. the explore page is based on follower count.
4. capital letters in username: maybe one day.. but i feel like lowercase, limited usernames are the "pure" form of usernames. display names might come eventually though.
