[2019] Cannot Post or Reply on any WoW Blizzard Forum Pages

Over the past YEAR I have been trying to figure out why I cannot post anything on the Blizzard WoW Forums. More specifically on the Guild and Classic Forums. I have tried swapping main characters, using different web browsers and devices, and still, no luck. It has been bugging me for a long time, and I am no long just gonna push it aside and wait till it magically fixes itself. I want to know how to fix it. I have a US account, using a US Forum page, no parental controls, everything authenticated, everything. Some forums have even redirected me to a different forum page to post and I still can't. What is going on?
