Instagram is dealing with a minor headache right now — cleaning up the junk you don’t want to see. The Facebook-owned photo-sharing service is purging old, inactive and spammy accounts, the first time it has done so across its entire user base. I was tipped off late last night after opening the app, when I noticed a pop-up message in my activity feed. You’ll probably see the same thing soon, if you haven’t already. In a nutshell, Instagram is warning its users that they may see a drop in their followers, due to a purge of the bogus accounts. “After receiving feedback from members in the Instagram community, we recently fixed an issue that incorrectly included inactive accounts in follower/following lists,” an Instagram spokesman said in a statement. “We believe this will provide a more authentic experience and genuinely reflect people who are actually engaging with each other’s content.”
