Impersonation feature bug / lack of documentation

Hi,
I just wanted to point out the following (which I relate to a bug) :

When you create a new server, set up correct permissions on channels, and you impersonate @everyone role to realize tests, then you still have access to edit your own posts, even though you shouldn't - since @everyone should not have any permissions, because they didn't accept the rules, and thus they don't have any role.
So, whith this in mind, either it's a real, rather annoying bug that should be fixed, or it's just normal behaviour that should be documented somewhere (sorry but I didn't find any documentation on it).
The cool part is that you can't, as @everyone, *really* edit the owner's posts, such as the rules. So we're safe :sweat_smile:
Have fun !
