You are quite correct on people doing those things, especially now. I've actually started to flag the ones that I see spamming it on post after post. They'll figure things out quickly or be flagged down. While I'm still a huge fave of the latest HF, a downside to be dealt with is that these people do get rewarded more for their bad behavior.

I'm sure we'll adapt to deal with it though. The same thing happened last year and eventually got put down. :)
