Hey, just so you know, it seems that you've been hellbanned/shadowbanned. So when you're posting, most people can't see you or respond to you, and your posts are automatically flagged and "killed". It looks like it happened about 7 months ago when you posted some comments about not liking Nazis. Very strange that you're being punished for being vocal about disliking Nazis!
