Yes. Blizzard runs the forums here and if people do not follow the Code of Conduct, and their posts are reported, the Mod may opt to remove the post/thread and also action the poster.
You can find the forum guidelines and the link to the Forum Code of Conduct here in the pinned post at the top of the forum.
It is not sometimes what someone says, it is how they say it. Name calling, insults, slurs, profanity/masked profanity, etc are not ok. Nor is flame bait designed to just create arguments and fights (religion, politics, etc). Stick to the game discussion on the forums and be polite.
