On the other hand, if you judge a source of criticism is going to be a waste of time, then it's fine to skip it. Not because you would ever ignore or disregard a criticism without thinking about it, and definitely not due to disliking criticism, but just because you reasonably expect they'd give criticism you'd already considered and rejected, and you have better things to do that you judge will bear more fruit.
The reason I'm not too worried about drowning in low quality criticism is that if there is no new information, it only takes a few moments to properly address. You don't have to ignore it because it's such a fast process. Just remember your take on the subject, verify that it already addresses what's being said, and then you're done. Don't even reply. But I don't call that "ignoring it", since you do quickly think about it, and if you notice there is something new to you, it will get proper consideration.
