Thank you for reporting! The player is already banned, but please keep in mind that you would have to include evidence that shows who the owner of the plot is for the evidence to be considered sufficient.
Unfortunately, the evidence isn't sufficient. One video needs to show the player mining towards 4+ veins of diamonds, and that video needs to include the full Minecraft window. Thank you for reporting nonetheless!
Thank you for reporting! Sam_13245768 and Humiliations have been punished accordingly. In future reports, please include timestamps for videos that are over a minute or two in length.
