I don’t like the concept of Link Credits, Link Clubs or “Click a bunch of random links and a slew of random websites will link to yours”. You can be certain the Search Engines don’t either. Get real, folks.
I’m always surprised that the search engines haven’t YET penalized everyone swapping links mindlessly. In 2007 Google clamped down on Link Farms. But of course, now in 2011 ”link farms” have been replaced with variations of the same. They’re a bit slicker now. And harder to detect. But still gimmicks whose sole intent is to boost link popularity for better rank in search engine results. My advice is to avoid any bad practice or you will get burned.
