I already attempted to change the admin user in the lemmy.hjson by switching the login information to a different account, but it still tells me that I'm not the top admin when I try to purge a community. If this isn't something that I can change, this should be something that is possible to do.

Although I don't know Rust, it looks like the function in the source code for getting the top admin is just getting the first user in the list of admins, is there some kind of database trickery I could do to achieve this?
