When Instagram Stories launched, everyone, including us, questioned if people would use it in the same way as they used Snapchat. Many Instagram Stories posts are still more carefully curated than those on Snapchat.
For example, if two users aren't friends, only recently became friends, have no mutual friends, interact with each other very little, have a significant age difference, and/or are located far from each other, the tool pays particular attention.
In fact, just a few months ago, Facebook complied with a police subpoena by sending over 62 pages of photos, Wall posts, messages, contacts, and past activity on the site for a murder suspect.
For more information about Facebook's stance on working with the police, I checked out these two pages: Law Enforcement and Third-Party Matters, as well as Information for Law Enforcement Authorities.
The app’s video and voice chat functions, along with similar service imo, now can’t be used in the country because of “regulations”.
It isn’t clear exactly why the features have been blocked in the country.
