You're using my position to construct a straw man claim of "All internet mafia is badly designed." and "All mafia relies on another person's face.", and then attacking me using that misrepresented position. If this is where you want to take the argument, consider this my last post on this thread.
It is exactly as I stated - this system in this context relies on emotional tells from another person's face, or other physical feature. Without access to any of that, this forum's mindset becomes heavily limited due to their overreliance on using roles in the most efficient way possible. Roblox's strategies are likely more different and adaptable to this sort of system, but this forum's attitude towards mafia still clearly makes this system impractical - the majority of players don't try to figure things out until it's too late and thus the mafia had an extremely easy time hiding and misleading others.
