Hi
@StrawberrySeed welcome to the thread.
Yes this has already been discussed. Doria went to prison for tax avoidance which is why Meghan was with her father. This record was expunged at a later date. I believe that this is because it helps ex offenders (who are not a risk) in terms of access to jobs. This had nothing to do with the Royal family and they might not have known about it.
As for Meghan it appears that a lot of erasing went on before she married Harry. This may have been done with help from the 'men in grey suits', we don't really know. There was evidence of her being a yacht girl and an escort at Soho House. Also claims that she did a porn film at some point. I don't know the technicalities of how you do this as I'm not a techhie.
We think that Harry insisted on marrying her and kicked up a fuss when he was challenged. The obvious answer is that the 'race' card was played.
It's absolutely appalling that he was allowed to marry her but we can only conclude that con artist Meghan pulled a blinder
Personally I wouldn't care too much about Meghan's past if she was a kind honest and decent person but it's the constant lies that makes me angry and her inflated sense of her own self importance (narcissism).
