When I published “Is Research Outreach a rebranded Research Features” yesterday, I went to Research Outreach‘s Twitter page, which is linked from their homepage. I was going to tag them in the tweet accompanying the post, since I like to let people to know what I’m saying about them. To my surprise, I found that I had been blocked. The reason this was surprising is that I don’t think I had followed them. I certainly never interacted with them.
