Two layers, and the first one is stupid on purpose.
The automatic filter
A word list. It hides messages containing things that have no business in a sale — abuse, and attempts to move the deal off the platform.
It is blunt. It will occasionally hide something innocent because a word appeared inside another word, and it does not understand context at all. That is the trade: a filter that catches most of the bad quickly, and a person for everything else.
If yours was hidden and should not have been, say so.
The host
A seller running a show can remove somebody from their own chat. That is their room.
What a host cannot do is remove a report, hide a review, or stop you raising an order problem.
A person
Reports go to somebody who reads them and decides. What that looks like.
What is not moderated
Prices. A high price is not a rule violation; the room decides.
Taste. We do not referee whether something is worth it.
Reviews, except where one breaks the rules — a review is not removable for being unflattering.
Questions people ask
Why was my message hidden?
The word filter, almost always. It is not a ban.
Can I appeal?
Yes, and say which message.
Does the seller see reports about them?
They see outcomes, not who reported.
Who moderates the sellers themselves?
We do. A host moderates their chat; nobody moderates their own conduct.
