Which kind of illustrates the lazy aspect of the trolling the OP was attempting. Basically, lets go at a few obvious candidates (like the Rovers who were everyone's idea of a joke team until recently but who, it pains me to say, are now a tidy and improving outfit) without actually checking whether their track record supports the assertion.
The fact is any team playing in the 2nd and 3rd divisions don't need to justify their existence if they're balancing the books, paying their players wages, providing an appropriate venue for their home league games and turning up for matches. Using example teams which have been doing considerably better than that just makes the OP look ignorant (which, in fairness, may have been an intentional part of the trolling schtick).
