Based off of the screenshot provided I don't see enough evidence to warrant a ban. It could have been intentional and covered up, and it's possible you could be experiencing continued harassment. However none of that seems apparent from the screenies.
If further proof is brought up in the future you can make a new thread. Feardorcha_Mac_Marbhaiche, consider this a warning to watch the teamwounding. If it comes out that your teamwounding is intentional and targeted a ban is a near certainty.
Locking thread.
