Re: Sen Dick Durbin To Zuk "Are you comfortable....on that BIG cushion, short-arse?"
As a NON-USER of Facebook / Instagram, I just have 3:
If you're in the UK, have you considered investing a tenner and making a subject access request to the company? You might need to provide some context beyond your name that would enable them to identify you/your data/your connection & devices, but potentially they don't need that because they could have bulk cross referenced your shadow profile to (eg) data from bungling clowns like Equifax.
If they come back with anything, you request its deletion and confirmation that they have done so, and acknowledging that you specifically prohibit them from collecting or retaining data about you in future.
Could be interesting - whether we'd believe their responses and/or promises is of course a separate matter.
