FREE Facebook/Adwords coupon Method for promoting appz 2015 :D

Now I'm asking you if you know any other free method of getting some traffic on the mobile games, at least on their release if not constantly.
I'm 1000% sure there are thousend of occult, FREE even more effective ways to get free advertising than those facebook and adwords coupons so if anyone could share one I'd be deeply gratefull.
I tried before, for about 2 months, to create PVA facebook accounts and join groups and post on them using a self made bot.
Beside the fact that it wasn't an efficient method, the bot slowed down after more then 10 active accounts, that I had enormously hard time getting the proxies, phone numbers, verify them, complete them, manage them and finally as a small present for my work all got banned and that I currently cannot create anymore facebook accounts because I always get the verification even If I create them on a private vps/vpn/proxy, everything worked perfectly well!
This might be a divine sign for me that I should focus on something else for promoting my apps than fighting facebook


Ok so briefly if anyone knows another working method of getting facebook or adwords coupon, no matter how black it is, or any other efficient method of getting mobile traffic please let me/us know.


Have a great day!

you should have added a question mark to your title >>>> "?" as I think many will believe that you're actually sharing the methods not ask about them
Also... i guess most people won't share such methods in public like this even if they know them.. so you shouldn't have your hopes up for many replies..

Ok than I should reformulate my question/request into 2 parts:

- does anyone know if there are any methods of getting free facebook/adwords coupon at this moment (just to know if I should waste anymore time looking for them or not)?
- can anyone share one of those 2 via PM?

Thank you!
