You just can't call people autistic when you're complaining about them and wonder why you're perceived as ableistic. Also you can't just telediagnose someone based on a few interactions. Autism diagnostics take hours of interview by a trained diagnostician. As an autist, you should fucking know that.
And you cannot repeatedly break a forum's rules and expect to not get banned. You probably got permabanned because you broke that forum's rules once too often.
Next thing you do is go to a language specific forum and demand them posting in english. You're just boneheaded if you expected that to work.
