I am no longer participating on Swap-Bot. I will not be responding to messages via the site. I've grown tired of the behavior noted below and have decided to focus on sending via SendSomething.net, where I don't have to worry about such things.
My philosophy on swapping is we are all adults and as adults we know there are risks in all areas of life. If you swap, know there is a chance you won't get something in return. Sometimes it is because the other person is an idiot (the world is full of idiots). Most times it is because the other person has stuff that happens that takes precedence over sending a postcard or letter or some other bit of expected mail. If you don't get a swap, rate a 1 without comment and try, just try, to understand that sometimes life is difficult and some people are not as capable as you at handling life's difficulties. The "bad swapper" groups and blacklists I see ALL OVER this site are just another form of bullying. It is a shame people can't deal with disappointment and must take their inadequacies out on those who may be already hurting.
And on the subject of "bad swappers," please do not message me to tell me there is a "bad swapper" in my swap or group, or one that is thinking about joining my swap/group, or peeking in my window, or dating my boyfriend, or abducted by aliens and now back and out to destroy civilization by cheating people out of a bit of mail, or any other detail relating to gossip/hearsay read on the forum or in a blacklist group.
