What is the best reason you have blocked someone?

One time, I posted a selfie, and this dude named Skidrocks downloaded the selfie and then started posting it all over SW. Which was super creepy. And then to make it worse, he started stalking all of my posts and whenever someone left a comment at me, he'd reply with "Stop talking to my girlfriend, asshole!"

She called me disgusting and blocked me. Symmetrical response and all.

He kept leaving passive aggressive comments on folks' posts. How petty can you be to decide to do something like that because YOUR life is miserable? I'll never interact with him on this site again haha.

I got an angry private message once supporting the sexualised spanking of children and telling me that by interfering with their body parts graphically explained, that it's "helping" them stay out of prison later in life. I said well it's not going to help you stay out of prison and reported and blocked them.

Harassment.

Did once briefly because it seemed the right thing to do. Then he blocked me and I unblocked.
I hate blocking people, personally.

Because they kept shitspamming on my posts.

They're an avid drumpf supporter.

Teaching a lesson.
