Used stamps exchanges.

I thought the club rules were: 100 used stamps, no duplicates & no damaged stamps. If you abide by these rules why are some people giving low marks just because they don't like the stamps you sent. I send stamps in good faith. I'm not a mind reader & I don't know which stamps you already have. I've never given anyone less than 5 stars, even when there have been a lot of stamps that I already have. They abided by the rules so 5 stars were given.

I agree. If people give you low ratings they should at least tell you why. I have asked people why, but they don't answer.

Hey Mike,
I completely agree with you - I see the clubs as a opportunity for random exchange while still supporting the postal services. In my case, there are no active philatelic societies in my area and I see this as a nice way to swap some stamps around. Given the circumstances, and having in mind that I have not been collecting for decades like other members, I don't have so much variety, but I try to make a decent mix and follow the rules. I even add a couple more stamps.
But yes, the penalties for low ratings (1 and 2) are a bit harsh in my opinion. I mean, you can agree to send more stamps but they also take their time to get to the recipient. In that time you are limited to only 2 traveling letters. That is not so big of a deal in 100stamps. club, but having only two 25stamps.club letters traveling seems absurd.
Still, I feel like the community is sensible enough to avoid giving bad ratings. But maybe it would be good to make comments and photos required when giving a bad rating.
