No Mo' Stalk[in]': HackDay Winner - Judge's Write-In (Every Big Social Network Should Have One)
LinkedIn is the only big social network left where you cannot completely block a member from looking at your profile. Having a stalker is a real thing, and we have no ability to allow members to block their stalkers. It's unnerving to see in your email or profile sidebar: "[Your stalker] has viewed your profile." Or maybe you have a headhunter that won't leave you alone and is really adamant that you're ruining your career by not responding to him. This hack fixes this problem, and lets you block members who are being unprofessional in a professional social network.
