I don't have the skills to do this but if I did, I'd definitely be giving it a go! Seeing as I don't have the skills, I'm not entirely sure this is possible but if it is, there's a lot of money to be made with it I'm sure! Please could someone clarify whether this is doable? To bank hard, you'll want to do this NOW as there is all the hype. Skills needed: app development skills (or hire someone else to do it) 1) Download flappy birds for Android or Jailbroken iphone. 2) Sign up to an app advertising site. Modify flappy birds to have your advertising code in it instead of the developers. 3) Create a site called something along the lines of "Flappy Bird Revival", write a bit about how you're sad flappy birds has been taken down so you've uploaded it for everyone to use. 4) Put a download link to your modified flappy birds game that works on an android or jailbroken iphone and downloads the modified app and clear instructions on how to download it to your phone. 5) Create a twitter account for your new site with the same name eg "Flappy Birds Revival". Tweet a few things, put the download link in your bio and make sure your latest tweet is a link to download the app. 6) Use a twitter bot such as follow liker to follow everyone who tweets the phrase "flappy birds", and favourite their tweets. 7) Set the twitter bot to do this automatically every day so it's a set and forget method! Also, possibly scrape some tweets and get it to tweet a couple of things a day without a link and then your link so you don't get spam detected. 7) Create a load more twitter accounts (and possible mirror sites to go with them) and do the same. 8) Bank from the ads. Also, if your site is legit, people will tell their friends that flappy birds can be downloaded from your site and it'll spread naturally. Again - I don't know if this is possible so can an app developer clear it up and say whether this is a valid method or not?
