Babs started OF when she was 31, a common age for people to step out their comfort zone for a bit.
She probably chose OF cause she has friends that know that platform and it's the biggest platform.
Meg Turney started going nude cause it was the progression of cosplaying, I'm pretty confident 30 summin year old babs is doing this for confidence and any "pushing the boundaries" is just her doing bare minimum to stay relevant.
RT has been her only job I think, so maybe she works for a corporate company, hates it, then turns to OF for freedom.
