So, something to add to this discussion. Instagram recently updated their TOS and this article (
http://bits.blogs.nytimes.com/2012/1...-mean-for-you/) highlights the main issues. Basically, the issues are as follows:
1. Instagram can share information about its users with Facebook, its parent company, as well as outside affiliates and advertisers.
2. You could star in an advertisement — without your knowledge.
3. Underage users are not exempt.
4. Ads may not be labeled as ads.
5. Want to opt out? Delete your account.
I have a feeling that the TOS might be somewhat different in Canada and other countries (as they have some stringent privacy laws) but the US will definitely be victim to this and most people probably won't even realize it.
