That site is cutting and pasting content from other Argentina blogs and tourist related businesses. Also entire news articles from well known publications. I do not see any people in the conversations who seem to be real.

Not a good look for his real estate business. Without ethics. Why would anyone contract his services when he is claiming on Twitter X to have fraudulently built up his new website?
