I think this may just be a misunderstanding on policy, or perhaps there were special circumstances involved. Technically, anyone can report anything for whatever reason they wish, or no reason at all. Generally speaking, removing someone from a group isn’t considered against policy.
Overall, whoever is the group/raid leader may remove whomever they want for whatever reason at any time. Assuming there was some kind of agreement involved when you joined, that might be something we would look into. If that were the case it would be reported as a Scam.
Keep in mind, if we believe a potential violation of our scamming policy took place our staff will investigate and take appropriate actions for any violations found. We won’t be able to share the results with you, nor would it allow us to provide any of the loot that you may have received.
Edit: Just to be sure. We are talking about normal grouping and the ability to remove another member of the group/raid? If so, the above applies.
If we’re talking about the Vote to Kick system, then no, it does not violate policy for someone to use the Vote to Kick system to nominate or vote for someone to be removed.
