(Sorry for bumping!)
There are many Roblox employees, who left Roblox, like @Hippie_ofDoom, @nightend16 or @OuterspaceNemo.
Those are not anymore in the “Roblox Staff” Group, but there post were official.
(I think) @Hippie_ofDoom was a DET and was actively responding to BugReports, etc., however newer Users can’t identify them and that is a Problem.
I think Abcreator means them
