@bruni - As far as I can tell, you can delete the names of those people that you follow, but you have no control over the people who follow you. I too have a number of people who follow me that haven't been active for months and a few for 6 years.
@bruni what's the problem exactly? are you clicking through everyone who follows you for some reason? Anyone who you follow that posts photos will show up on the home page feed and there's no need to click through to each persons page.
@Scrivna can answer this one.
