Is your comment correct?

I quote people here many times, I add a link to the original comment, and I only do when <allcalps>I</allcaps> think the comment is correct. [1]

If it's correct, it's not poisoning.

[1] Or maybe when it's wrong and I explicitly say it's wrong. But that is usually not nice, so I don't do that too often, or perhaps I never did that.
