I addressed a lawyer. Positive answer. No direct association.
I guess all the lawyers will say that too, the main developer or operator is the one who has the burden on all the cases because he is commissioning a campaign to pay people to promote.
Majority of the campaign here do not have affiliate code so they are not really earning from commissions only from posting and showing the banner from their signature campaign, maybe if they are actually leading people or recruiting people directly and they made money from recruiting like they do on Ponzi schemes like Bitconnect, then there's legal liability.
The laws differ country by country, but there should be a general understanding of the whole scenario.
In my country I have seen ponzi schemes and/or scammers who advertised on national TV and Radio stations and in the end when the scam must have manifested, no agency went to the radio stations or TV to sue them or implicate for whatever reason.
I think that should be our fate in this forum, unless other countries policies differ.
