Colloquial usage
The term "Whac-a-mole" (or "Whack-a-mole") is used colloquially to depict a situation characterized by a series of repetitious and futile tasks, where the successful completion of one just yields another popping up elsewhere.

In computer programming/debugging it refers to the prospect of fixing a bug causing a new one to appear as a result.[8] In an Internet context, it refers to the challenge of fending off recurring spammers, vandals, pop-up ads, malware, ransomware, and other distractions, annoyances, and harm.[9][10]

In law enforcement it refers to criminal activity popping up in another part of an area after increased enforcement in one district reduces it there.[11] In a military context it refers to ostensibly inferior opposing troops continuing to appear after previous waves have been eliminated.[citation needed]

It has also been applied to fake news, where as soon as one story is debunked another appears elsewhere – or sooner.[12]
