I think Vashalar is confused with how the forum works which is fair.
To give them the benefit of the doubt.
Having your post hidden by other users takes five flags, so five individuals feel your post is breaking the rules. Spamming the same topic over and over is against the rules as Epideme has pointed out.
Once a post has five flags it can no longer be flagged further and has to wait for a moderator to review and decide if it’s rule breaking and if so take action they deem appropriate.
If a moderator feels no rules have been broken, they can unflag a post so it isn’t hidden when people first open a topic. A hidden post basically just requires an extra click to see what it says. However the system will notify you that your post has been flagged.
Moderators can also decide to lock at topic if it has descended into too much bickering (insulting other players, circumventing language filter etc) and general rule breaking. They can also delist a topic, so it no longer shows. Rule breaking posts are often deleted to remove them from view. People who are actioned may also receive a time out from the forums. Those ‘forum vacations’ stack up so if a person frequently misbehaves they will find themselves taking longer and longer breaks. If you get a forum vacation you will get a notification and you will get an email confirming the reason for your punishment and a link to the post concerned.
Moderators are staff employed by Blizzard and their text appears in blue. They are the only ones with any power on the forums. MVPs post in green, we are regular members of the community who are generally helpful and polite. There are plenty of lovely regulars who are also very helpful without the benefit of green text. On the US forum the Community Council members also get their own colour, which is a kind of golden yellow.
If you are struggling with any aspects of the forums and it’s rules there is a pinned post in this forum that tries to cover all the bases.
