Some people or mostly people noticed that some fans are very addicted to their idols like putting to much posters in their room, putting their pictures in Facebook or Twitter. Well, this will help your problem.
To the addicted fans, try to control your addiction because I was an addicted fan also but I learned to control by putting my head in my studies first but I have time for my addiction.
To the people that noticed and are very worried, try to understand them and tell them to control it the right way. Don't shout because this will cause a very big fight.
