The correct option is: "When exchanging QSL cards for contact or reception confirmation, you should fill in information such as 'Eye ball QSO', and should not send blank cards." I understand that if the above description applies, filling in information like 'Eye ball QSO' or other relevant details (such as online card exchange or forum card exchange for remembrance) can be used as commemorative gifts.
My attitude is that I don't initiate exchanging cards, but if someone sends me a card, I will return it. However, when filling out the details, I do hesitate because I haven't met them in person and don't know what to write. Perhaps marking "QSL card for remembrance on hamcq forum" would be appropriate? But I think there are only two situations for QSL cards: either as proof of contact or reception, or simply as a keepsake, like the eyeball card. Therefore, with the development of the internet age, initiating online exchanges for keepsakes is not necessarily unacceptable. In any case, whether it's an eyeball card or a network card, their purpose is only to be kept as a memento, and they won't create a hierarchy between them.
Therefore, I believe that practicing the principles of "consideration, loyalty, ambition, friendship, moderation, and patriotism" as a hobby is not an error in principle, such as creating blank or fictitious QSL cards. This type of online card exchange does not necessarily have any problems; however, if it can be linked to real communication in the future, that would be even better.
