Hello PandaPuncher,
Overall we don't permit Threads dedicated to advertising on these Forums. Even if the Discord is Terraria related, it is still advertisement of a site used for Terraria discussion which can be done on these Forums. Off Topic Threads are required to have discussion about a non-Terraria Topic.
Because of this, we have locked your Thread and removed the link. The only places appropriate to post your Discord Server are on your own profile, or inside your signature, which can be added from your account settings. You may feel free to repost the Discord link in one of those 2 places if you desire.
