Yes and no
Yes some donated cards (or paid if forward) and I am very thankful to them, but I'm sure if you ask any one of them if they expect someone to hold on to the cards they sent simply because it was donated, I'm fairly certain they would say to do whatever ever I wanted to with a card if 1, it wasnt something that I particularly collect or 2. if I had multiple duplicates of the same card. I highly doubt that you have every single card you ever had. No not ALL of my cards were gifted. I would generously say maybe 3500 were gifted, and that number is extremely high. If you take a moment to look at my collection you will see well over 25,000 cards. I have given away easily the same amount of cards I was gifted. There is nothing wrong with using this site for what it is here for... buying, selling and trading. Unless that only applies to people who have never had a card gifted to them.
