Maybe you should add some demo video so people can see how your ad network platform would work in real life.
Fraud is not possible in Bitfari, I repeat, it's not possible.
I saw that it is possible to earn Bitcoin by reviewing Bitfari ads, so my question is can anyone participate in this and how are you going to fight with fake reviews and abusing with multiple accounts?
In theory someone can create hundreds of accounts and write multiple ads feedback to earn more Bitcoin.
