If I had to guess, said link is more than likely sent to a Discord server or something of that sort via a webhook to be reviewed, therefor not violating any standards because a user on the platform never saw it.
Even ignoring that and assuming it is displayed to staff members in the game, you can make a reasonable assumption these staff members are 13+ users which means that, again, they wouldn’t be violating the standards because Roblox explicitly allows developers to display links to select websites in game as long as the viewing user is permitted to as PolicyService dictates.
If you’re gonna try and call out someone for breaking ToS or guidelines, at least try to do proper research on the subject first.
