This was my exact PM to him:
The wording here is a bit weird, I used "negotiate" instead of "collaborate" but I really meant that I was willing to help on the OT, not steal it from him. I felt I was polite in my request, I didn't feel I was pressuring him into doing anything.
This was sent 1 day BEFORE he redacted his statement. I waited 2 days for his response, he did not PM back I just assumed he was not interested in making the OT any more so I booked the OT to avoid this in the future. Today I wake up, guy makes a post how he is not happy and he has contacted mods (again without PMing me). He not only didn't PM me, he didn't make a post in the gaming side about it (I am sorry I don't visit Community as much). Today someone had to point out to me that I was demoted.
*shrug*
If it were me I'd probably bug a mod about it, you getting Junior-ed for that feels like a pretty big overreaction or simply a misunderstanding.
