Seeing an unreviewed provider really doesn't take any more trouble/work/expense than seeing a girl with reviews, What it does take is a lot of "risk tolerance"
I travel outside the country a LOT, and I travel to places where P4P is legal and there really aren't site like TER where you get to read reviews of the women you see, but OTOH there is ZERO risk of LE, so TOFTTng is a much lower risk proposition.
I have no problems at all seeing a woman who I don't know how she will perform BCD, I have no problems risking a B&S as I can simply turn around and walk if she isn't the hottie I am expecting, What I am rarely willing to risk however is seeing a BP hooker, with no reviews, in a setting that just screams "LE Sting"
Come to think of it, ALL of the SB's I meet are technically TOFTT, and I try to meet at least a couple of new ones each month, so I guess I am pretty open to TOFTT, although it's not really taking one for the "team" as I am not doing it for the rest of you, so it's more like "taking one for myself" lol
