I agree. Journalists often have a bad habit of reporting "new trends" that they hear about from other journalists, who heard about the trend from still other journalists, who heard about the trend from the journalist who made it up!
This is probably harmless if we're talking about "new slang words that teenagers are using"; it's not so harmless if the journalist is reporting about "the growing epidemic of babies born addicted to crack cocaine."
(The "crack-baby epidemic" is one of the more famous examples from US journalism of a non-existent problem that was invented by one journalist and then became an obsession for news media nationwide. Actually, there really was an "epidemic" -- but it wasn't a new problem as a result of "crack" cocaine; it was the same old problem of Fetal Alcohol Syndrome that had existed for decades.)
