Instagram is a hugely popular social network centered around sharing retro images with friends, and while it continues to add users by the millions, it will likely soon see a somewhat sizable defection in light of recent events. Facebook co-founder and CEO Mark Zuckerberg on Monday announced that Facebook will acquire Instagram for $1 billion. The deal will make Instagram’s small team rich and give the app exposure to millions of new users, but it will also bring a fresh round of privacy concerns that have already begun to surface. For those who avoid Facebook and its suite of services, deleting an Instagram account couldn’t be easier: users can simply visit the company’s account removal page, log in, and select a reason for their account removal requests from the drop-down menu. As it turns out, “privacy concerns” is the very first option.
