I have already said in my introduction, I do not want to receive the German stamp. If there are only a few, I will not give 3 stars. But these are German stamps and there are no stamps from other countries.

If I say I only want stamps from Greenland, should I give 3 for everything else?
his profile is a lot more flexible than yours, your profile almost exclude 50% of issued stamps. maybe this where just the stamps he had, have you asked him.
even though I probable have all those stamps, I would have rated this 5 stars as Federal Germany is really good to swap by want lists

what we say in our profiles is just a "wish"
club rules are here fulfilled so you need to give more than 3
