Try change your Bio to "You are beautiful", that works.
Try then change your Bio to "You are amazing", does not. It automatically changes it to "youarearloking" all-lowercase, spaces removed and some characters changed.
Update: After further debugging it seems like it is the "mazi" part of Amazing that is triggering the filtering. It was suggested this is in relation to blocking of the word nazi. Pazi works but Mazi does not.
