Unfortunately, for this Teamspeak report, it would be hard for us staff to locate the player with that username. Although the evidence is indeed valid, we cannot do anything about it due to the fact that we cannot locate the user. If you have any evidence of this player repeating their actions, report it again and make sure a moderator can assist you right away to handle this issue, before the player changes name. If they change names, make sure you have a screenshot of the time when they changed usernames. Sorry.
Thank you for the report. Unfortunately the evidence provided is insufficient. Should you gain more evidence in the future, do not hesitate to report this player(s) again. Kind regards, The Staff
