This rule not about faucets, is about all sites/games with rewards/compensation program and faucets is most extreme example of such sites.
And where we can get official information about your company? Registered company name, office phones, post address? You request sensitive personal information from users during registration, but not provide any real information about your company.
The Publisher has the right to place a maximum of 3 (three) ad units on a page and only 1 (one) of each size allowed (for example: you can place 1 x 300/250 ad, but you can't place 2 x 300/250 on the same page).
This rule only for ad blocks from your network? You allow the same size ad blocks, but from different networks on one page?
