I was trying to figure out why we saw so many fraudulent applications from Vietnam for a service which is restricted to the United States, especially because they were all getting rejected - it seemed like even the laziest spammer would lose interest in something they couldn’t monetize.

A guy in Vietnam mentioned that one of the largest ISPs there used these really dodgy Chinese modems which were so notoriously insecure that it was apparently common knowledge that you should replace them if performance was slow because that was a sign that yours was being used by a botnet. Apparently the cost of access to one of those nodes was so low that the spammers don’t even really monitor their bots.
