Sad thing is that most of the older established sites are so riddled with penalties & other negative ranking factors that it's relatively easy to launch a new site, pepper it with links, enjoy some candy then crash & burn.
Then just 301 the links to a new site. Rinse repeat.
Unfortunately most of us are attached to our brand names.
