I don’t know why you think the links you’re giving in both posts about this is insecure?
They redirect to https.
And you really need not post twice about the same thing.
If you got something from PayPal then I would think your questions are for PayPal. If you used them to pay with they know who you made purchases from. Perhaps it a PayPal promotion.
BTW, cartloom and Weavem I doubt keep any of your payment information PayPal or other payment gateways are the only ones that get access to that.
