My honest answer to your question is "I don't know if a forum member ever has".
But I hope not. At least, not one that says Gibson on the headstock.
If you are just talking about cheap copies, then that's fine. If they are not branded as Gibson, then it's fair for anyone to take their chances.
There are a couple of things anyone considering this should be aware of, though...
Regardless of what any YouTube reviewer may say positively, these are quite simply not cheap Gibsons. There have even been preposterous claims, such as that Gibson setup a Chinese factory, built a load of guitars, changed their minds and that these guitars then somehow found their way onto the market. That is sheer nonsense, and never happened. The people making those claims are usually the guys (or working for the guys) selling them.
Even if, though, you buy a guitar not branded, it is virtually guaranteed that you will be getting inferior woods and inferior electronics.
People go on about the build quality being great, and indeed it often can be. Labour is cheap in the Orient, so a lot of labour can be spent fitting and finishing the guitar so that it looks great. But at the end of the day, it will have cheap woods - not mahogany, maple and rosewood, but cheap alternatives that may not even be considered tone woods. The fretboards are often softwood stained to look like rosewood or ebony. Also, you can pretty much guarantee that none of the wood comes from sustainable sources, and the working conditions of the people who make them will not be regulated.
The electronics will almost certainly be substandard. A vast amount of the tone of a Gibson comes from the electronics. The pots and capacitors in the genuine article are expensive, quality items, and it makes a huge difference. Let's not even talk about the pickups!
If someone wants to buy one of these then this is what they should be aware of. They would be getting exactly what they are paying for: a cheap guitar. But definitely not a bargain Gibson.
Of course, none of this covers Chinese guitars actually branded as Gibson.
They are simply illegal.
