A slew of new swap-bot postcard assignments are coming my way today. I’ve received most of them, and my eyebrows are raised. One goes out to a user in Australia to whom I just posted a few days ago, and several are to fellow users here in the U.S.–including one who lives as close as 20 minutes away from me!
So it seems that swap-bot doesn’t have any controls to prevent repeats–if even at the very least in too close a time period–or to put a minimum distance between members. Over at Postcrossing, all of the correspondence is international, and there are enough members that you get a new pick each time. At swap-bot, you choose your swaps, and are limited by the number of people who enlist in each one. This means that, although I’ve only signed up for swaps marked as “international,” I’ve been given a lot of U.S. addresses for my outgoing cards. The repeat, and the super-close member, make me guess that the user-moderators of each swap make the assignments, and not some complex algorithm on the site.
