Might be worth noting that this should all be covered by GDPR, at least as far as the legal names are concerned.
Part of the GDPR says they have to make sure their data is up-to-date, and only the minimum required. If a name changes, it's no longer up-to-date and they're at fault if they don't change it in their database, including scrubbing any reference to previous names.
Another part is the right to have all your info from any other party scrubbed.
I know the GDPR doesn't apply to parts of the world like the US, but there are repercussions for breaking it over here.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
