I disagree with this. There is absolutely _no_ difference between mass-importing thousands of articles and a person sitting down for weeks mass-importing thousands of articles. The only check the latter imposes is "someone has to have too much free time to do this", which is not much of a check at all: there's all sorts of crazy things people are willing to spend time on that are quite trivial. And there's all sorts of important things people aren't willing to spend time on.
To pick a relevant example, I'd consider any of the six million people who died in the Holocaust more encyclopedia-worthy than the ~3k that died in the WTC attacks. The fact that there are people with enough spare time to mass-import the latter doesn't change this fact.
