I like the concept, but it's not something I would run personally unless there were a lot of checks in place.
Yes, would certainly be needing of some checks. Perhaps a dictionary of acceptable link-words that would be OK to "click". Maybe also a blacklist of "never-click" words and/or domains/netblocks.
Or even perhaps a whitelist of a few domains that are OK. Chances are slim that Time.com or USAtoday or CNN links would lead to trouble and the collection of "safe" links would grow exponentially with only a handful of "safe" domains.
