There are polite and impolite ways to express skepticism, and I'd encourage anyone to give Ruiu the benefit of the doubt as far as his motivations are concerned, even if you can think of an uncharitable explanation. "Here's some odd behavior I've seen and a possible explanation" is far from a hostile or irresponsible thing to say, especially when there are long histories of state-level and non-state level bad actors engaging in behavior to warp the target's perception relative to observers' of what's going on.
