There is literally no connection between GamerGate/Kotaku to NuTSR. The folks at NuTSR have been trying to bring up other controversies in gaming to try and force personal connections to them. It's nothing but a weak attention grab.
They tried to make posts claiming they were somehow connected to the Phoenix/Stone controversy; when
@Jedion357 managed to contact Phoenix directly, she said she had never heard of NuTSR. They tried to channel GamerGate; Lanasa's father, William Gentry, wrote an article about how the "attacks" on NuTSR are "GamerGate 2.0". But literally nothing posted makes any connection with the original GamerGate whatsoever. Earlier in the week, they tried posting about someone catching COVID at GenCon.
Most recently, they're trying to post about the "Daisy Grant" story that's coming out of GenCon. No doubt this one is high priority for NuTSR because it involves a trans person. I've only read the basics of the story, but I can guarantee you NuTSR has no involvement in it. One of the links they posted goes to a subredit heavily associated with GamerGate.
NuTSR is desperately trying to link themselves with any controversial news item they can find. Unfortunately, the only way to fight it is to ignore it.
