In fact, this is really a bit ridiculous. To take a step back, even if these companies are doing the distillation, they are doing it through intermediaries or data brokers. They wouldn't say that their own company is using its own IP to distill your data. Moreover, mainland IPs are not allowed to access it. For real data brokers, you can check out a Weibo user named Liang Bin; his company specializes in this kind of dirty work. Haha.
