Yeah i recently became aware of the same site after my little brother was trying to find a 1.13 download. It was the first link that comes up when googling it. The site tries to almost exactly copy the real one so it can trick people, especially younger ones. I took a look at it, it seems to just try install a bunch of junk on your computer. Probably trying to get ad revenue money or something. Not extremely dangerous, but would prefer if something be done to get it taken down.
