We can’t help you. Sorry. Try rejoining every now and again to see if it’s any better.
You seem to be one victim among many appealing bans that are being falsely attributed to the appellee, where said false ban victim is from the Philippines (according to basic IP data the forums shows to admins, see the privacy policy for more information). This has been a problem for a long time but we haven’t seen a lot of it coming up until very recently. Unfortunately, because of how limited Terraria banning details are we aren’t able to lift the ban without also unbanning the intended target who was banned for a valid reason, but the problem might also fix itself seemingly at random.
Currently I’m drafting a basic post to put out somewhere in this category so players, especially those who are affected, can at least be aware that the problem exists instead of needing to find an explanation like this buried in someone else’s ban appeal over why they randomly have someone else’s ban stopping them from playing.
