So looks like Fyber singled me out, and perhaps a few other players. I still have not seen a single offer except 1 crown videos. They of course denied the whole thing, and tried to blame it on location, device, and some other random factors. My other 2 accounts get tons of offers, on the same device, same browser, and same location. The only difference is that advertising id or whatever they use to identify you. Nexon customer support is unhelpful as always, shifting all responsibility on Fyber. And Fyber already told me to get lost. This is unfair business practice and both companies should be held responsible.
I hope Nexon can reset my advertising id since Fyber won't do a damn thing.
