Is there any way to permanently block a member from a guild. We have to kick two people consistently for trolling our guild and filling up our chat with stupid messages just to annoy us..
Try setting your guild to ''Join by request''. It is the only solution as of this time. Perhaps you could also take a screenshot and report them to the Midoki Team.
I believe if you kick someone out repeatedly, or deny their request, there is a bit of a cooldown before they can attempt to join again. Thats at least something Otherwise reporting them to Midoki in extreme cases is the only real solution, or maybe putting the minimum pirate rank above whatever the troll's rank is.
