Hello, in my understanding, "revenge ratings" should not be accepted on this platform. I sent a lot to one member nearly three months ago and he did not register it. Yesterday, I registered a lot that I received from the same user. As it contained mostly CTOs (and my profile says explicitely that I do not collect them) and no interesting stamps, I gave a negative rating. One day later, "coincidence", the user suddenly registers the stamps that he pretended unreceived for three months. Of course, he gives me the same negative rating, complaining that I sent him too many CTOs. It's true that I sent CTOs but only precisely from the countries from his wishlist, as I only had CTOs from this countries to give. I had even asked him whether he prefers CTOs from these countries or normal stamps from other countries - no answer.
What I want to point out is the practice to wait for my rating and then "suddenly" register my letter that seemed having disappeared for three months. This kind of revenge is for me not in the spirit of this website.
Concerning the CTO-question, I think it's also not fair to punish me with a sending of random CTOs that I am clearly not interested in while I only chose wishlist-countries' CTOs for someone who does not explain that he does not want them...
