“If you can’t find the original post of that graphic and REBLOG it, then don’t post it. You’ll just have to do without it on your blog. Simple as that.”
That is the biggest load of crud I’ve ever read. If you’re so presumptuous as to write something where you are telling someone what to do then you are incredibly stupid.
If the original creator doesn’t get the notes on his/her blog that doesn’t matter. What matters is that the picture gets notes, and so the creator will still get feedback just the notes won’t be on a post on his /her blog they will be on another users blog.
