I think it is a legally binding, but please see below: https://ibb.co/CHNQVCP

Countless SE'ers have signed that type of document without Issues.

There's no declaration, affirmation and nothing of the sort to verify that what you're saying Is true and correct to the best of your knowledge - which Is what holds ground with legally binding documents. All they're stating Is "legally binding declaration" without anything supporting It.
