It seems some people are still not getting it. So here it is again...
It's becoming tedious having to remove unhelpful, heckling posts from adverts.
Do not reply to people's adverts unless you intend to post a question about the item, or make a helpful comment to add information about the item or otherwise assist the sale.
examples of unhelpful comments include: "Your price is too high", "I can get it cheaper from XXX", "You should never have bought the dog" etc.
If you have a genuine grievance about an advert or concerns about the item or seller then use the report post function. It is the button under the post which looks like this:
Unhelpful posts will be removed and if they continue the account in question will be suspended.
