It’s too bad for Maxxelli, because they actually do a lot for expat families and others who are here for brief stints. Most of the corporate people who roll through go through them and seem satisfied. I am pretty sure they hired a couple Chinese who went about standard spamming procedure for most Chinese-run websites/web-based services. Having said that, Chinese employees will do what they are told/shown to do, so it is up to management to set an example.
What gets me is how stupid the spammer was. I mean, all you really had to do was use a VPN and change locations, or recognize that you can be traced. But that speaks more to how things are done here than to the actual intelligence of the spammer.
