Have you ever gotten a message on here that makes you not want to share things anymore?

Yes,

But I also have seen comments openly displayed on posts that are vile. I just saw one today on a person's post that was so vile in response to a post that was completely neutral.

I blocked and reported that person, and I feel like I've done it once before some time ago.

There is a whole lot of human pollution on here.

Also , I'm so sorry to hear that someone did that to you and made you feel this way.
