Absolutely. I assume that the way people treat other people is a reflection of moral character, and therefore tells me something about how they treat their animals as well. If someone can't put effort into thinking about how their written words will sound when read, how much effort are they putting into making sure their snakes always have fresh water or keeping accurate records? It might be an erroneous assumption on my part, but I also just don't want to deal with or encourage rude behavior.
