What's with all the posts randomly mentioning Alibaba all of a sudden?

I don't know if anyone else has noticed but there seems to have been a huge uptick in posts that mention Alibaba, the chinese e-commerce site, on this and other writing subs. No way is that organic, they all read like bot posts - some generic fluff about writing, then drop a mention of freelance copy writing right in the middle. Even worse, people are falling for it and engaging with the spammers!

Mods asleep at the wheel? you tell me.
