We accept all legal traffic sources: SEO, PPC, social networks, forums, doorways, etc.
We don’t accept spam and branded traffic.
Traffic sources are closely monitored. Sanctions might take place when the rules are violated. But that doesn’t happen often:)
Also, note that the niche is not accepted for contextual advertising on social networks, meaning your account might get suspended. Before you launch a campaign, get in touch with the support team to get advice on how to begin working with different traffic sources safely.
