For Christianity Haven, we don't need a lot of staff since we don't have a lot of reports to work, so there's the owner (not me), Admin (me) and another staffer that both the owner and I have known from another Christian forum for well over a decade now. We trust him and his judgment and he's been on staff for years.
If we had to hire again, I'd go with someone I know from other forums and trust. I wouldn't hire someone fresh out of the gate because they can really do a lot of damage that could go unnoticed for a long time if you aren't checking.
