I'm sure something good came out of this.
GBOs are basically another middleperson. They take a cut from the sale. The only difference is that they are easier to dox than a Chinese vendor being more local and all.
Actually if you wanted to do real damage to a Chinese vendor, all you need to do is expose them on Douyin or Rednote. Chinese people are brutal when it comes to exposing scammers, cheaters, and such. The entire country will know. The only issue is finding out the real name and the face associated with the vendor's ai image.
