I used an old laptop that I had. It can be run on a raspberry Pi.

How do you keep nefarious actors off your relay? Child porn, violence, etc? Is there a way to automatically police that? Trying to think of legal implications.
Right now it is a private relay and I choose who can write on it.
Are there risks to running a private relay?
I mean public
Since there is no cost to access, read and, more importantly, write to these relays, spammers and bot accounts will naturally gravitate to them.
Are there systems in place to help block spammers?
