Re: If I lived outside the US
If I posted a link every month or so it’d be vastly more usage than my actual social media accounts that I don’t use.
I’m sure they’d work out your real accounts from any email addresses or phone numbers you provide them anyway, even your address is likely enough for them to know your accounts. Adding it to a form is likely a way for them to tell if your lying or not.
Far easier to assume they know everything as the US tech companies have to comply with us law regardless of jurisdiction, just as the us are accusing Huawei of except us companies are under continuous compliance.
