There should be a Tumblr meet-up day, where everyone rallies at some fun location and during which everyone awkwardly pussyfoots around whether or not to speak to one another.
Then you could Follow your favorite people around wherever they go (like on a ride or something, if it’s at, say, Disneyland) or you could remain Anonymous by pretending like you’re not there for Tumblr Meet-Up Day and talking smack (presumably to yourself) about the people who are willing to admit they are.
Such a day wouldn’t be creepy at all.
