Are you familar with the term 'white hat'?

Hello everyone. Are you familiar with the term ‘white hat’? It’s primarily used in the computer industry especially in the field of SEO (Search Engine Optimization). If you are a white hat, or do things ‘white hat’ you follow Google’s mantra “Don’t be evil”. Anyway, have you ever heard that expression or even started using it?

Many thanks,

It is not a sentence, Nidichinametla, but the phrase is OK like this:

I remember talking and hearing about the good guys in white hats at least 40 years ago, Torsten. It’s an old idea that has simply been adopted by a new industry. It used to be connected to cowboy movies. You could identify the good guys because they always wore white cowboy hats, whereas the bad guys always wore black cowboy hats.

In addition, Dodge (automobile) used to use an advertising slogan back in the 60s that went like this:
You can tell they’re good guys – they all wear white hats. … arger9.htm

Of course, these older usages may be fairly restricted to AmE. :wink:
