Generally korg world is a small world. Over the last five years I only remember one malicious "org" forming in what I heard was a disgruntled monger who decided to harvest mongers pii so he can enter some other orgs he was denied access to.
So it wasn't even a real org, just a harvester of info.
If you are aware of the rentry list, it's under the #scam hashtag there.
Unlike indies, Korgs are usually spinoffs of someone who was in the business one way or the other. And with present realities of immigration nuances, it's difficult to get new talent. New local orgs generally are going to be mostly established kgirls just traveling the country and looking for new markets.
My advice - ask someone in the area or close by. If you're on west coast or in nova, feel free to post the agency here and you'll likely get an opinion from someone who is a frequent visitor and not new to the game.
It's not that often that a new korg forms so generally I wait for confirmation it's indeed a korg (once again, kgirls and po's and owners are plugged into kgirl networking) a few toftts if it's new talent (usually the talent is rebranded anyway).
You don't generally get an early adopter benefit besides the off chance that there might be an exclusive gem. But news travels fast anyway and word gets out fast if a kgirl is of good quality.
If you're worried about b&s or pics being very much off, definitely don't toftt. This will happen regardless of the org at some point when a girl is using pics that are off.
I suggest in order to get info on who'd you like to see, read some reviews and know what you like and go into that direction.
Don't have expectations super high looks wise. Most kiglrls are in their 30s and up. Pics can be very off or outright fake.
I will say, most new kmongers who dabble with indies off other sites, are usually pretty damn happy with what they receive in a korg.
