The post was started in April 2015 though. Is this still working in 2018?
Why it wouldn't buddy ?
Instagram exists, facebook as well, as many other website where you can build up a community.
There's still people trying to grow their community, and most of them are ready to pay shout out instead of fake likes.
Fake likes are even harder and more expensive than before, it's good for you.
There is not a lot of way for a method to get useless, one is the cops, another is being saturated and the last is that the website/application don't exist anymore.
I wish you luck !
