A dog named Scamp

That is not a valid defense.

What are you going on about?

Bruh. I deleted the comments because they were dumb shit like this: http://m.imgur.com/LOm7ERG,hedYvIk,Ecf94nw
If people want to give constructive criticism on my posts that's fine,but if they're literally insulting me,and saying "this is dumb",then I feel that I'm more than justified in deleting their nonsensical comments.

Not correct. It is NOT justified to delete someone's comments just because they say something you don't like. Constructive or not.

Lol really? Then tell me,when IS it justified? If someone was sending me a death threat,and I didn't like it,would I not be allowed to delete it?

Yep. Death threats are also an acceptable reason for reporting. However that was not a death threat.

I know it wasn't a death threat,I was just using that as an example. My point is,why should I have to keep up rude and irrelevant comments that contribute nothing to this site,and nothing to my post?

"...you should just stop posting."

Now I'm not gonna confirm anything. But I work as a moderator of a few servers and that's often a death threat.

Death threats are death threats. "You should just stop posting" is not a death threat without significantly more content providing that implication.
