Prez_Obama started randomly team wounding me while going up the ladder, then along the wall he tried more with his scythe, then decided to try and keep team wounding me with a knife on the stairs.
Here's some screenies:

I didn't do anything to provoke him nor have I even seen him before, so I'm not sure why he did it (other than to grief).
Anyways, thanks for reading.
Edit: Noticed in the screenies that Mechanix said Prez_Obama is team wounding in chat, so maybe Prez_Obama was team wounding multiple people.
