I would like to start a website with contents like : warez (and lots of others "grey" contents and discussions topic), right now my server is in a DMCA-proof hosting (russia) and the domain name registered in china, however I want to monetize my website in a smart way and I don't want to use classic ads banner or related. I want to use "advertising captcha" and they are not a lot of companies (only in : Canada, France and usa) offering this type of "service", I have searched and searched but I can't find a russian or chinese one... So, here we are : I want to use an american advertising company, live in europe and can be in trouble in my country, can I really be in trouble if they find me or it's ok ?
Talk to a specialist lawyer The advice here might be enough if you fly under the radar (ie not very successful) But the moment you start making a Kim Dotcom sized impression on the market you may find things get nasty. You may be 100% in the right but the "other side" can throw enough legal crap your way to bankrupt you before you even get to court.
I do not have a personal problem with warez, but to me it sounds like it is more trouble then it is worth. I would love to recommend you focus on a site that is more "legal". Nearly every ad network worth recommending, states it does not work with warez sites. regardless what advertising company you find, you may have issues if they cannot verify your address. IE, you could earn money, and then not be paid, fake address etc. Or do you really trust them with all your personal details. Here is what i found in google, use at your own expense. List of warez ad networks Note by linking, I am not encouraging you. Personally, I would not trust any of those companies with my email address, let alone my personal details. Have you thought about doing something with bitcoin. Such as, user downloads rar file (containing files, or information), which is locked. you email unlock code, after they have sent bitcoin payment. Or you can have locked content, (pages, or VIP area), unlocked when they pay membership fee. Can you agree to advertise other warez sites in exchance for cash? Even footer links can be worth a few $$$. Can work well if they are in a slightly different niche to you. Basically, you do not have to rely solely on ad income for revenue. I think that "sarahk" made a good point when she mentioned "kim dotcom". Not to scare you, but kim dotcom had lawyers, had everything setup 'legally', yet the US was powerful enough to have him arrested in a completely different country and dragged to the US.
