Hi please how do you target desktop only on Juicyads?
Is it possible to even target just windows / mac?
THX!
Are you running RON on JuicyAds or running on a specific placement?
As far as I know, this is not possible with juicyads. You can buy mobile redirects/popunders, but if you go for banner traffic, its gonna be a mix of mobile and dekstop.
Hmm?

You can find this option under Stats & Settings tab (after clicking Manage). I am pretty sure you can choose it while creating campaigns as well.
Weird, I cannot find this option no matter how hard I try 
Im inside a banner RON campaign, clicked the stats&settings tab but dont see anything about traffic type & os targeting in there.
It's right under Google & Alexa targeting for me.
Try to create a new campaign. This targeting option is a new feature and old campaigns could not have it enabled.
It is possible in the newly created RON campaigns. If you have an old campaign, you can ask them to update it for you, at least they did it for me.
Guess you already know this but Juicy is obviously only for (hardcore) adult campaigns
If you want to get more specific targeting in place or buy very specific placements for your campaigns, you should get in touch with an AM over there. Hit me up on skype if you want me to bring you in touch with them.
They are great people and very helpful
