We cannot accept evidence that has been edited (or drawn on for this case). Do you have the original screenshot?
What Clxrity said is true, we cannot accept screenshots that have been edited in any way. This also looks like they were talking about finding you and killing you in-game, which is not bannable. Now if they said I will find you in real life, then they would be banned. Im closing this for lack of evidence, 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
