I've been thinking about it. There is absolutely no way at all Shane is RbW.
Shane is confirmed to be conspiring with people on discord.
Renfamous is known to conspire with her little betas on Facebook, Twitter DMs, and presumably other areas.
There's no way Renfamous didn't take one look at Shane, see a gloriously exceptional useful idiot, and figure that she could use him to organize some confusion.
Shane is not fucking smart enough to be spewing the shit RbW has been doing so. RbW's tweet style is the exact same as Renfamous's. RbW was created when Renfamous was suspended for misgendering herself. Is RbW Renfamous? I think so, but we'll never know until the cardiovascular disease kicks in and takes her out.
Watch: Going forward her defense at being accused of being RbW will be some variant of "lol really? I thought RbW was Shane. You stupid kickvicker nazi pedo capitalist alt-righters just can't get your delusions right." She could even do so in response to a discovery request. "That's not me, look, YOUR OWN SIDE thinks it's Shane."
It was all about creating plausible deniability.
