I worked for one of those companies that created user-generated content (UGC) marketing platform. The basic idea was picking images from Instagram (IG) and feeding it to the client's site so that they could have the lookbook page. I am not an IG user but was surprised IG exposed these images for anyone to use. The original poster on IG has no idea something of this sort happens. If I recall correctly the client can also use the images in FB ads and stuff. I understand some people using IG want fame and stuff but I just felt we were stealing people's pics and making some profit out of it without even telling them and it just saddened me. Every time I was asked to work on a feature I would just start questioning myself WTF am I doing? Is this what I want to do?
