i lol'd at the lmfao.
No, but seriously, you are right in a sense. People do just post random useless replies for no apparent reason other than to boost their post count, but this is a forum and it's kind of expected, really. These people lurk the earth and it's something you need to just live with. Moving on to the vouch copy part. Yes, I agree on this as it would kind of put a stop to some of the shit posting, but in reality, it won't do much.
At least when I shit post, I make it funny or kind of constructive. *ahem* ^
