So ggrevolt being ggrevolt as usual. Shame about Shadist being outed, best I can advise is for them to stand their ground. As long as they're fake, lies will never stick. Now if they did hit or were close to the mark, the target should lie low and pass on sensitive work to trusted accomplices.
Also, they really need to screen their mods. These things happen because there's always a mole involved.
