@levisan i think a lot of time it's just privacy orientation — someone who wants to feel free to post what they like on the account without mystery strangers following along. (esp if they or someone close to them has been burned by creeps/stalkers before)
@sabbatical Interesting, so you see it as a "I don't want people snooping" more than a "don't follow me" signal?
@sabbatical Aha I suppose not being offended is the key point!
