Hi, why was i banned? I've been inactive for a while but I dont remember doing anything bannable. Is it because of my username?

This is quite funny, as you seem to be one of the first people who is ACTUALLY banned for seemingly no reason. I'm afraid I cannot find any reason for your ban, nor can I find a log of it on our Discord Server. I'll be unbanning you now. My apologies for taking so long with this, I do not usually look here.

I'd say this game has quite a good PVP system. I like that.
afanguy (Topicstarter) on 9 Dec 2020, 14:07:59
I am glad you enjoy the game's PvP-system. I'm pretty proud of how it turned out.

Hello, I've been banned from this game for a bit and I honestly don't know why. I haven't been on for a while because I've been trying out other games also, so... yeah.
supermemes64 on 30 Aug 2020, 21:30:36
I still love this game
afanguy (Topicstarter) on 9 Dec 2020, 14:07:25
None of the logs state anything about you being banned, sorry. Are you sure you're banned?

Howdy! I'm just leaving this message here in case if someone has met me in [Mysterytale Online] and wants to have some sort of contact through GameMaker Server. Sometimes I add people in the site from fangames I play. Hope that anyone I once addressed to contact through here will see this message!
