It's a secret curse word that is too offensive for respectable company like this.

There's the only thing I can think of is that the people making these made them to post on facebook and Instagram, and so they have to comply with their absurd puritanical morality system.

You can't say fuck. God forbid the word fuck is shown to a 13-year-old. But f*ck? Perfectly fine.

And because they are so pervasive throughout the world, their rules have filtered into other social media.

It's insane, and we should kill every single person that complies with those rules.

We hang enough heads up outside of the lemmy servers, eventually people will get the point that they can say fuck on this website.

I can only assume it's a regular expression matching zero or more "f" before "uck"

• uck
• fuck
• ffuck
• And so on...
