I think the idea that it is the door hurt him is speculation.
I agree about not linking to thesun. I've actually seen it forbidden on another forum (as they had run trashy lie 'articles' related to the subject discussed there. Kremlin might know it, based on his avatar). I think banning is extreme, but discouraging it makes sense as the page being linked to is just clickbait.
I recommend just hotlinking to the image you wanted to share. The fact that they make it difficult to do makes it all the more important to do so. :)
