Just because we have put in the effort & know, does not mean every single person knows & many believe pizza gate is a farce due to Fake News claims.

If enough customers on the site send support tickets/messages with links to evidence that pizza is a pedo code & that there is pizza being sold for the price that children are often sold, or rented, for then those companies will know their customers are aware of the issue.

Many of these seller sites are a way for small business owners to make some extra cash. If we go on a crusade to tear down every single one of them that have bad listing's pop up, we will only be left with Amazon/Alphabet agency approved shops. This would only benefit the big online stores that can more easily be controlled by a few well placed managers.

edit: It certainly could be a honeypot.
