Then when I comment (reblog) on thoughts or images of others, those people immediately know. All without spam and other complexities.
I dunno how long this lack of spam will last. I mean, if someone creates a spam tumblr account and just re-blogs all the posts by other popular users (adding links to their sites in their reblogs), then their posts will show up for all those who follow the people being re-blogged, and unlike comments, there’s nothing the original poster can do to remove this spam.
We recognized this possibility when creating it, but haven’t seen any spam so far. It’s not a very attractive spam venue: HTML is stripped from Notes in the Dashboard, and they’re limited to a very short, summarized length.
Rest assured that we’d very aggressively remove any spam that cropped up.
