Possible problem :
Say if I set chitika ad code as my preferred ad solution, and an user set google adsense. It would be quite obvious for both of us, whose ads are being displayed and all resulting consequences.
Though there is provision to filter ads by html and adsense only, this would effectively reduce advertising solution to adsense and html only, and users hay have their preferences for ad solution that should be respected.
I would like to discuss possible solution to deal with this situation.
