I think verbal abuse is a subjective x on the number line of criticism and said feedback. Some people can handle getting called shit, and some people think it's the end of the world. To answer your question, no I don't think when putting something out in the world you're consenting to verbal abuse. I think you're consenting to unmitigated feedback (if it's an online forum, perhaps), and sometimes that feedback will come in the form of verbal abuse - whether that's someone's right or not to give said feedback, I can't say.
