What's with all the YouTube fakes?

I saw at least 3 different videos claiming that RPCS3 can run Final Fantasy XIII and XIII-2! Now someone sent me a message after I called BS that they are going to show me "Xross Media Bar" loading with Camstudio! Why are people claiming this emulator can do things that it can't yet? Is this someone trying to deface/avenge this project?

people are stupid
sometimes they do things without any real reason

Sometimes they fool people (probably children) into downloading rpcs3notinfactabitcoinminer.exe, so there is that...
