It is sometimes said that if something seems too good to be true, it usually is. For conspiracy theories etc that are argued for on social media, this applies to a particularly large extent, it seems.

It appeared at an acquaintance’s house on Facebook yesterday. And seemed, just… A little too good to be true. Not unlikely, because somewhere the house with that name must have been, but…

Otherwise, there are several websites that specialize in reviewing and exposing rumors and outright lies that – in good faith, or completely deliberately – are spread. Snopes is one, and in Sweden there are Faktoids and Viral Reviewer. But often it goes a long way to just type in a few well-chosen words + “hoax”.
