There's nothing wrong with PR firms. Without PR firms, lots of companies would never get their product any visibility. Sure, there are a few who don't have any integrity, but Skymark isn't a PR firm. They are an investment research company. They aren't blasting PRs out to anyone but their customers.
I suspect another round of a smear campaign is coming. Not a big deal though, since we've already seen it weather through shorts, smears, and a couple panic sells. It's always come back strong. This time around we can shrug it off a little easier.
