It's frustrating when you encounter situations like these in competitive online games, and it's understandable that you feel frustrated with the system in place. However, there are a few things to consider:

In many online games, there are systems in place to prevent intentional or unintentional team damage. These systems are meant to create a better gaming experience for everyone and minimize disruptive behavior.

The intention behind these systems is to discourage players from harming their own team, even if it's not always the result of malicious actions. Sometimes, accidental damage can occur in the heat of the moment.

When it comes to being kicked or banned, these systems often have strict thresholds to prevent abuse. This means that even if you didn't intentionally team-kill, if you accumulate too much team damage over time, you can still face penalties.

It's essential to report any griefing or toxic behavior to the game's support or moderation team, as they can take action against players who intentionally try to disrupt the game experience.

While it's frustrating when you find yourself kicked or penalized for circumstances that feel unfair, it's also important for the game developers to strike a balance between minimizing disruptions and avoiding false positives. The system might need to be continually adjusted and improved to address cases like the one you described.

If you feel strongly about these issues, providing feedback to the game's developers and participating in the game's community discussions can be a way to help raise awareness of these problems and potentially influence changes in the system. Remember that it's not always easy to find a one-size-fits-all solution, but developers usually appreciate player feedback to make their games better.
