You do have to let it go at some point though: just like one chooses to trust your Mom & Pop’s local merchants won’t duplicate your credit card while scanning them under the counter, you have to expect websites to treat your private information respectfully.

Amazon just sent me an alert saying another user tried to make purchases with my credit card, which they had previously linked with my account over there. I didn’t expect them to actually make proactive checks like these and was pleasantly surprised.

I have yet to understand when my card information was harvested and if transactions were made on other websites, but at least Amazon’s suspicion will be noticed by my credit card provider.
