Unfortunately, my pixiv account (ID 4496510, @jez-mm) has been suspended due to rules about off-site linking I was not aware of at the time. Despite their customer service team assuring my account would be restored if violations were resolved - and my taking a great deal of time to edit external links out of all of my 10+ years of works uploaded there, I have recieved no response from them. Looking into this, it seems to be a common experience for users to never recieve any response or closure over account suspensions, so this situation may remain permanently.
