Sometimes I've seen a "source" given that didn't actually support the claimed point. I think I've only seen that with a single source, though, not multiple sources. But when asked for a source, they just dropped a comment containing a URL that was superficially related, and someone had to take the time to actually
read the link to find out that it didn't actually support the disputed point.
In fact, the whole "a lie can get halfway around the world before the truth can get its boots on" idea might be considered a variant of this. Making fine-sounding claims is easy; proving that they are false is harder. If you make claims faster than they can be refuted, you can get at least some people to believe you, even if much of what you say is false.
