The average listener who sees "FOB Reuniting" in their news feed of whatever social media site is going to see that and be like, "Oh, cool, word," and then see the denial and lose interest. Bottom line: management/the band are shooting themselves in the foot right now.
Also, not to sound nasty, but it's not like the Tribune is an untrustworthy source. It's a respected newspaper, therefore, what they're saying is probably fairly legit.
Haven't you heard of deny, deny, deny until you're caught?
