Can I do a joint venture where I allow someone else access to my account for a share of profits they generated?

No, this is directly against Dynu In Media ‘s affiliate terms and conditions. Just like selling your affiliate account, the bulk of those interested in joint ventures do so with the intent of defrauding advertisers. A publisher is solely responsible for the leads generated on a campaign. Should the second party in the joint venture generate fraudulent leads, it’s the publisher who risks account termination and litigation, not the second party.
