trading items between characters

[Akai]

There is a rule that two characters of the same player cannot trade items, I know, because they do not know each other to arrange the trade. But, if one character posts a public notice of items for sale, may a second character arrange to purchase those items through a mutual acquaintance? If so, what safeguards would be appropriate to prevent impropriety or the appearance thereof?

Thanks!

Character 1 may post something, and Character 2 may respond to the post, but they'll never be able to meet to complete the deal.

Muling is muling. Just don't do it, even with a second, third, fourth, etc., party. Everything can be tracked. Even between worlds.
