In my opinion you would be correct to create a page and category for this fraud. There are already profiles affected by it
Back in 2014, the parents of Henry Whitney, Whitney-63 were removed . His parents were Mary Roach (Roach-313) and Thomas Whitney (Whitney-550). Though Thomas is mentioned in the article, the name of his wife is not. Ellen posted a note about the fraud in May of this year
But was left behind when it was inlinked in 2014 is not labelled in any way so still a trap to the unwary.
The line from the unlinked Thomas (Whitney-550 ) goes back to the Penelope Pardoe mentioned in the article along with her father William and her husband George Whitney. It does not appear that these people existed. The wikitree profiles have no sources and none of the detail from the fabricated wills and IPMs ,many are orphaned. However, with no warnings in place and no category linking to a description of the fraud there is nothing to prevent someone adopting them and fleshing out the incorrect detail. More pragmatically, there is nothing to stop the sheer waste of time involved when some unfortunate sourcerer stumbles across the profiles and spends time trying to find sources in England for them.
I have no idea where Mary Roach originally came from and whether she was named in the original fraudulent book. Nevertheless I suspect that what is there would also not bear any scrutiny.
(Her parents are named as Sir John Chester Roach and Lady Margaret Elizabeth (Elizabeth) Roach formerly Gay aka De Lisson
Mary Roach also has sister named as Lady Dorothy Dameron (formerly Roach ) .Dorothy is married to another emigrant * with a whole flood of descendants in the New World who will link back and into the Whitney/Pardoe line
* Lawrence Dameron. On his profile it says " nothing has been documented about Lawrence before he received a land grant in Northumberland County, Virginia, in 1652" His wife seems to be a Dorothy but I suspect she should be Dorothy Unknown.
