I remember once having a long discussion with Jack Knave about the most more egregious inaccuracies on Paul Nuttall's LinkedIn, and how even if someone is filling it out for you, you have a duty to check it for accuracy. Given this is not the only inaccuracy in Reeves's LinkedIn that has found, you would expect even basis common sense would have checked and covered any changes without them having to be flagged. As inaccuracies go this is relatively small, though the others have been more important but it doesn't give confidence.
