Couldn't get this working at first. First I thought it was because I didn't have an exclude forum (early bug mentioned in this thread), then I found you fixed it later. Then 180-odd posts in I found you don't PM when the thread originator moves their own thread!!!!
I don't know about you, but when trying it on our test forum, that seemed the easiest thing to do

Could you make it optional maybe? Or at least make it clear in the documentation?
It seems to be working at the moment, but I think there's a legacy message problem from a previous similar hack... Off to keep digging
