Hi All!
I have same problem.
Global mute / ban for all zones for new chars Imp / Rep sides.
I use short message promo "New casual guild LF Members" + guild link
Sometimes I answer to n00bz in general chat
Im polite and dont do bad jokes with n00bz
I had opened tickets #38514337, 38515797 but still haven't solved my problem.
I wrote to support mail because of after these 2 tickets I wasnt able to do new ticket.
All advices didnt help.
Like as reset UI, repair by LauncherRepairUtilityU2021.0.18.exe
I tried game with 2 different PCs with another locations and ISPs - no way, same problem.
I complitly reset n reinstall game - no way, same problem.
After near week I tired and was able to post "New casual guild LF Members" and had success
Then I posted "New casual guild LF Members" + guild link from another char in another new zone and after this I took ban/block again.
Both guilds name are simple and without something bad.
I still can post "New casual guild LF Members" + guild link in another zones except 4 zones for new chars (2 Imp / 2 Rep)
Before I posted same "New casual guild LF Members" + guild link in all these 4 zones for new chars (2 Imp / 2 Rep)
without any problem.
So I think that its wrong working of auto ban/ mute system after some new changes.
