I would have loved this to be true but the screenshot he sent doesn't provide any proof he has playtested the Sims 5 or any other game. I went in and registered as a playtester. Took me 2 minutes to get to the same screen he posted.

So yeah it's probably someone who just took a screenshot of the site which is very easy to access and claimed he playtested the Sims 5. Also I think anyone playtesting a game like this wouldn't be allowed to talk about it and especially on facebook where their name is visible they would run the risk of EA seeing it and banning them from playtesting ever again.
