Offline marketing works big time. I have a separate dept in my Company that market adult niches offline (especially those with $1 trial). Works very well for CPA. But the problem is that the conversion rate is too high so you need to seek permission from Affiliate Manager or the Manager in charge of the affiliate program and get a WRITTEN EMAIL confirmation that they are aware of your marketing technique. Remember no Skype conversation as proof, it must be email sent from the official domain. Example, maxbounty. That confirmation must come from maxbounty.com so they are legally liable and can be sued if they ban your account later (which they will anyhow since CPA Companies cannot shave when you use this method)
