I’ve read [citation needed] that some people enjoy doing it because they want to give (back) to the community and because they would like to try having to deal with anything from spam complaints (e.g. Automatically) and legetimate complaints and requests. Maybe also because “somebody has to”. :)

For me, my middle relay is sufficient entertainment. It’s like a digital pet that doesn’t need much attention except an update/upgrade about once or twice a month.
