Yeah - I came across two senators in my "people who submitted your details" list. Seriously what? How do they have my details and how is it verified that they got them legitimately? I'm in the UK, a UK citizen, have no contact with the US political system, and have only briefly passed through the US. So how have two senators got my details? The email address used is not my spam email, it is, as far as I know not used on sign up does etc. - so how was it found (though I am aware of the extreme irony of calling an email address used on Facebook as a not for spam one)? Facebook and all those who are on that list are going to get a GDPR request come the end of May.
