In attempting to source the putative rules quotes, I stumbled upon this intriguing page. It is a complete Spanish translation, and not a bad one at that, of our site's page - much like you will sometimes see a question copied word-for-word on quora. There are web adds on the page, so the most innocuous interpretation would be that this is just an enterprise to send bots out to harvest / scrape web content, translate it, and then sell web advertisement space (and perhaps promote the translation software, "Yandex").
While most of the poster's names have been changed (to give the impression that this is a legitimate site with actual members?), mine hasn't - and there is a link to my actual rpg stacks member page. Should I be concerned about this?
The page says that it is "Powered by StackExchange" - I doubt that arrangement is consensual. Does someone at StackExchange want to know about this?
Is there some aspect to this that is more sinister than selling web adds? Perhaps people who think this is a real community site make an account and then something is done with their information?
