Hit the "Report TOS" button. If Admin does not delete the posts, then they do not violate TOS.
Moderators have to follow the same posting rules as everyone else, so it's basically irrelevant who is a moderator as far as board posts is concerned.
You have the option to ignore posts, either by not reading them, or using the ignore function.
Moderators are removed if they flagrantly & repeatedly violate the rules. Posting opinions critical of the company does not violate TOS.
