I'm with the others here.
I personally honestly encourage donors to help, but if I'm trying to handle a situation, I prefer they leave it to me. Say for example, a group of trolls/etc.
If it's just one person here or there, donors drop their binds and warnings, ask about kicking, etc. I highly suggest doing the same. Asking to help is the best way to know about these things and when and where it's appropriate to help.
Communication is key.
