Oelewapperke posted a long and detailed reply to this post, and yet it will go ignored because all his posts are automatically killed without him being aware of it. His posts may not be perfect, but I still find this kind of false positives terrible.
It's not a false positive. He's hellbanned. Hellbanned users don't know they're hellbanned - their posts appear to them "not dead." If you look at his posting history, all of his posts starting 160 days ago are dead, and it seems to have started at a post from 175 days ago.
