This is why I refuse/back out of eshops that require accounts. Has the unintended upside that I often think twice about buying something and often dont. If I really need something though, ill create an account with a filler email, receive my product, and then make a really tedious (for the company) GDPR request because sometimes I like to be petty. Then I delete my account. If I need something from that store again, I will repeat that process.
