Why does an encyclopedia need articles on porn stars? They're all going to be the same thing - some fake biography from the back of a DVD and a list of movie titles. You can get this information anywhere. I'm sure if you tried to add any accurate info about these people you'd be reverted and banned for "doxxing" or violating BLP - remember that there is no such person as "Alexis Texas" any more than there is a "Captain America," these are fictional characters played by actors and writing about or interviewing them in-character is just LARPing.
It would be extremely funny to compare the bullshit info about people in porn to the real info (column 1: "said in an interview that she is a 'very sexual person' who wants to 'explore the art of seduction'", column 2: court records showing the real person behind the pseudonym was in family court 17 times before age 15 regarding child abuse complaints and screenshots of her texting a producer that she will do interracial anal for meth if it can be set up within the next hour) but this would never be allowed.
