The replies to his tweet with the link to the Guardian article on the children from countries in crisis. There was a girl complaining that he "censored" her reply. She seems to have deleted the tweet now (probably because of his fans) but she did republish the tweet that he censored (but without mentioning him). It's absurd because all she did was comment on the article by saying "shame on the UK" (I saw it before she deleted it too).
She doesn't look like a crazy fan but what do I know?
But I checked the replies to his tweet and I couldn't see any of the usual "I love you" and "follow me" so she might be right.
