I would report the user. Right now I'm writing a whole bunch of things, and I plan to be posting them all at once, just like you had. Go to dujo's page and comment about the user. I hope this helps (:
Well firstly, if you have something posted that's not yours and you've given credit, that's not allowed. But the whole being falsely accused, just lime the other users said. let an admin know.
That's not true at all. If you feel this user is harassing you, then I'd PM an admin like Audrey.
I've talked to Audrey before about plagiarism, and she said that if the editors or anyone got a report about someone plagiarising, they'd look into it first and talk to said reported Mibbian. You should be fine though.
