I wonder what the story behind this action is? It's surprisingly short to the shutdown, and they seem to indicate they wanted to keep those markets open, as otherwise I feel like they wouldn't falsely give people hope they might open it up again:

> We will review this decision regularly, and we hope to be able to reopen the BrickLink Marketplace to LEGO® fans in these countries in the future.

Shutting it down in (almost) the entire South America doesn't feel like it makes financial sense, can't be such a small market that it wouldn't be worth keeping it open.
