So last night the plagiarizer agreed to publish a specific form of wording (thanks to
legionseagle for advice) acknowledging he'd copied my work. Today I needed some time away from it, so I've spent my day buried in DWP stats. At 5:30 I spotted a message from a friend that implied he had posted something that wasn't what was expected. On checking I found he'd used the older form he'd proposed, but it still acknowledges that he used my article and presented it as his. Which he'd wrapped in about a page of text protesting that this wasn't actually plagiarism.
So I noted that this wasn't the agreed wording, pointing out what that was.
And he's been whinging constantly ever since. Apparently it was completely unreasonable of me not to be on Facebook all day, even though everything was agreed last night. (He sent a message at 04:57 saying he'd changed his mind) And it wasn't his fault. And it wasn't plagiarization. And noting what he'd agreed to say was unfair.
At this point I trust his behaviour so little I've screenshotted his statement in case he changes it later.
You would think I was dealing with a whining teenager who won't admit he was caught. He's actually a serving soldier.
