Not really. One of them was posted to gamedeals@lemmy.world and I managed to check it out for a while. They literally copied the official Helldivers 2 page, down to the publisher and developer names. Every little detail, even the “news” updates. It would have been very hard to tell that it was a scam, unless you took the time to read the reviews or the community forum.
I was on the community forum on there and there were a lot of people warning everyone and asking people to report them. One guy in particular managed to link to 5 other store pages that were posing as popular games, that all happened to release at the same time last year and change their store pages at the same time.
