Hey there, sorry to hear you're having this happen. We are aware of some players that intentionally cause team damage and have been looking into how we'd like to address it in the future. Now, there are times where it's difficult to distinguish, we get that, and are looking into that as well.
If it's something you notice time and time again from the same player or players, reach out to us with screenshots (or video if you can) of it happening and we'll look into it further. Thank you for bringing this up, see you in the Hollow Lands!
