Reading the rules for the forums would do that.
Politics, hateful speech that is sexist/misogynistic/racist, etc. are not allowed. Same goes with insulting people.
Further, posting about forum moderation is also against the rules. That is why threads keep getting locked and removed. Your post now, and Kiadaw’s, both break the forum rules.

Additional Forum Guidelines
Do not post about moderated threads.
Posts that are moderated have a reason behind the moderation. It’s up to you to read the forum Code of Conduct and these guidelines to determine what you did wrong, learn from your mistake, and attempt to post again without breaking any rules. If you have been subject to account action, you should receive an email detailing the suspension or ban to the Battle.net account associated with your forum posting account. Please refer to Customer Support for any inquiries regarding the status of your forum account.
