As someone who was a "bad" user (under another username); posting rather useless, short, unsighted comments and submissions; I think the best way is to "educate people".

I stopped bothering after a few incidents where content-free snarky bullshit written in response to my genuine comments was upvoted, and pg was unwilling to remove any of it.
