tantek on Flickr, Facebook, blogging platforms in general, if you block an author or delete a comment, it's gone from your post. On Twitter, it's only hidden *from you*. E.g. I blocked that spammer bear saw, and if you view this: https://twitter.com/t/status/490312706650431489 you will see it still has two comments from that spammer (I can see it on a non-logged-into-twitter browser)
