Like many internet abbreviations, IFK became popular through texting culture and social media shorthand.
People have shortened phrases online for decades because typing quickly became part of internet communication. Just like:

That emotional intensity is why younger internet users especially adopted it quickly.

Today, IFK is mostly used among Gen Z and younger millennials, although many older users now recognize it too.
