Instagram sent out an update this week explaining their services. This was in there: "We receive different kinds of information from your device, like how you tap and scroll, which can help distinguish humans from bots and detect fraud." Instagram tracks how you scroll. Bots do not scroll, they jump from link to link applying actions. Followliker and the rest of the bots are likely dead now. Unless you have a script that applies a physical scrolling (cookies can detect whether the input is a mouse, trackpad, or finger swipe) using bots is flagging your account for shadowbox or possible full ban.
