[17] - Who knows if the goods OP's selling are illegal in his jurisdiction and who will put their time watching on every buyer that visits OP's store. (Not that the spectater will have access to that info

)
Majority of illegal goods are the same in most parts of the world and there are publicly available information for what goods are illegal where.
If it's a store the trade is happening off the forum and cannot be moderated here, thus only applies to trades happening on the forum.
The OP isn't selling the products directly on the forum but linking them to a 3rd-party store.. Maybe a need for new rule.
That's a loophole, but if the trade isn't happening here, it will be difficult to check and verify. Have you encountered such a case and reported to mods without any action taken?
