Whether it's a parent checking in or a jealous boyfriend keeping tabs on his ex, stalkers are going to stalk. There are several apps that enable this type of behavior, and Like Patrol is one of them. The app scrapes Instagram data, allowing users to track who their targets interact with. According to CNET though, Instagram, sent a cease and desist order for violating its scraping rules, which will hopefully halt Like Patrol's ability to collect data, and force the publisher to shut down the app.
