I don't think he researched either his content properly. If you watch the video why Louise and Zoella fell out then watch the original video with Louise commenting on Zoella beauty it's all a big laugh as Louise mistook shower cream for moisturiser.GDFilms pronunciation of Isla and Esme proved he has never even watched a vlog
So I would take anything he says with a pinch of salt anyway. It's not hard to watch a video to get context but he hasn't and jumped on bandwagons
Like you say to not know how to pronounce the girls names, it also shows the intelligence of someone who pronounces Isla as Is Laah. Though I do know someone who did the same getting the name from a baby book! Not the brightest people on this planet
