How can anybody say something that is required to be "disclosed" if asked should be done in "private"
If a promoter wants to use a generic "third party" in their disclsoure, then they should be fully aware that somebody will ask for the full disclosure of who that "third party" is.
Doing it in a PM would make the publishing of that info a violation of TOS rules which seems to circumvent the entire "disclosure" process.
Asking for the name of the third party is not a violation of any TOS at all, it is completely on topic of any stock board as the provider of the compensation could/should explain who is really behind the promotion.
At minimum there should be 1 request made on the public board for the name of the 3rd party and that info then should be included in the Ibox for the duration of the promotion.
Not allowing anybody to talk about who paid for the compensation defeats the purpose of all disclosure rules.
