it's easier to fall for these messages because the blog doesn't LOOK like a bot blog, because it ISN'T a bot blog. it's a normal person's blog that got accessed by a bot, meaning the blog's content CLEARLY looks like a real active user when you click on it. and yes—it might even be a blog you already know. sometimes bots like this go down a blog's DMs or reblogs and message people they've previously interacted with.
