Roman numerals in character names for "Hollyoaks" (1995)

A short while ago, a member of staff responded to my post about the Roman numerals in character names for "Hollyoaks" and assured me that steps had been taken to stop them being added in the first place, so that I wouldn't have to keep removing them every week. However, they are still being submitted: https://www.imdb.com/title/tt16746784 https://www.imdb.com/title/tt16747338 https://www.imdb.com/title/tt16749672
