EDIT: I am not in that boat. This is purely an opinion that is based in decades old precedent of liability in carrying items or being the intermediary
As I said above, safex needs to keep in common carrier status otherwise any safex owner could be targeted by USA for enabling the illegal material.
What do I mean by common carrier? Think of Courier companies, or ISPs, they have common carier status because they DO NOT censor the material they transport/transfer based on any personal or caompany basis. They carry the item and the only exception allowed is personal safety (ie no explosives etc). If they were to censor the packages or data packets then they lose common carrier status and become responsible for ALL packages or data packets that they handle and if ANY are found illegal then that non-common carrier status company/person is liable to the full extent of the law. Its up to the police or customs to detect illegal material and not the common carrier status company.
So for safex owners to vote on content being traded is to open up safex owners to legal liability if any item is up for sale that is illegal in the country of the trade or where it can be sent to. The USA have shown in the past that they will attempt to get people for this very thing. EG The Pirate Bay owners, Wikileaks owner, the New Zealand guy who ran a big storage site.
Do you think that the USA will not go after safex owners if just one vile item is up for sale and the safex owners don’t vote it out. This could happen because we cannot vote on everything (billions of items).
So no do not expose safex owners to USA overreach who will attempt to arrest owners in countries like the UK, Australia, etc. safex NEEDS to keep common carrier status.
BUT DO vote on advertisers who have put up vile items for sale and ban them from listing ever again (and remove their trades obviously). You do not lose common carrier status because you refuse certain people from being customers.
Minor difference in what is being done, but a major one in our legal liability and potential to be arrested because of some scumbag getting an vile item past the “censors”.
The best list to check on is the international police list of things to pursue. This list is agreed on by most nations and represents the vile stuff that most decent folk do not want. Then ban the people who try to trade this stuff and don’t try to censor every single item put up for trade. Its easier to deal with millions of people than to attempt to censor billions of items put up for trade.
