I don't know if this issue has been discussed before but today by mistake I sent myself a PM as I quoted a reply from my outbox. I received a notification that I received a pm from "erikalui". I should be getting an error instead that you cannot PM yourself but why is there no error message? I just realized that I can also leave feedback for myself and report myself.
Can't these options for disabled for a user?
I think you cannot give yourself a *trust (positive, negative or neutral). For the question about the PM, yes it seems strange but you are able to send yourself a personal message (I do not know if it is a bug, but it could be useful - if you want to store something).
