UK citizens can also opt out, as the Data Protection Act 2018 is the UK's implementation of GDPR and confers all of the same rights.
In my opt out, I have also reminded them of their obligation to delete data when I do not consent to its use, so since I have denied consent, any of my data that has been used must be scrubbed from the training sets and resulting AI outputs derived from the unauthorised use of my data.
Sadly, having an Instagram account is unavoidable for me. Networking is an important part of many creatives' careers, and if the bulk of your connections are on Instagram, you have to be there too.
Forgive me for the pessimism, but I sincerely doubt that they honour any opt-outs. Meta has shown time and time again that they'd rather just pay fines as business expenses instead of abiding by law(s).
I mean, I guess maybe someone could take a picture of me and upload it to Instagram and label it or something. And it's possible to infer that two people are associated by having a picture containing both them that you run facial recognition or something on. I guess you could kind of think of that as being "my data" in an indirect sense.
