@twshield do you mean an option to do so without alerting them at all? I'd think even if they added the option you describe they'd still get a notification about the follow. I don't think unfollowing anyone ever notifies people either way unless they're keeping a close watch on their follow list and remember who theyre missing; it's a long shot. I believe there is an option in your profile settings to not send anyone a notification that you visited their profile at all, although I presume it'll notify them if you follow them under all circumstances.

@twshield now that I see why you want to do it you should just let that inhibition go. Assume that all our profiles are public and everyone has or is perfectly welcomed to dig into anyone's profile, that's why it's there. Youll never be able to limit yourself to going to profiles of people who have seen yours because you don't know half the people who have seen yours, so many of us probably turned that notification off already. Pretty sure I have but don't care enough to check. Anyways don't be a stranger, or do, or don't without notifying anyone, either way
