In the UK there is no "barely legal" it is either legal or illegal. All your question is asking is if you would be happy leaving children in the care of someone you knew had a taste for legal porn.You talked previously about trust - so I'll ask you (without reference to anyone you know - so purely hypothetical): would you be happy leaving children in the care of someone you knew had a taste for barely legal (adult actors looking like children) porn?
