Oh, yeah, you could totally upload nasty pictures. What I’m questioning is the original claim that people have been using these mechanisms to trigger automatic internet censorship systems to kick people off game servers.

An easy test for plausibility in these cases is: Can we prove a more extreme case?

Here the answer is: yes. People demonstrably SWAT others in online games. Victims have actually died from this. Yet it continues to happen.

So since the more extreme case - do people trigger police visits to other player's houses, knowing they may die? - is true, the milder case of triggering automatic censorship seems very likely to be true also.
