Hello!
Thanks a lot for the detailed explanation!
From now, while traveling, I will change the country of departure or create accounts in each country I visit, indicating the delivery address in the country of permanent residence.
Although I find cloning accounts is unfair to compatriots. This is especially true for Russia, where the limit is 3 postcards due to the large number of participants. I think it reduces the chances of receiving postcards from "rare" countries. I suggest paying additional accounts-clones from one address with donations to support the site development. It will be fair play. IMHO
Stay healthy and have many new EUROPA stamps,
Hidalgo
P.S. Sorry my English
