In essence, that is what you will be doing.
If research is done and you find nothing you are taking a risk. If it looks TGTBT, then it probably is.
I don't bother with providers who have a no review policy, especially newer providers.
LE should always be a concern, but you will be more likely to get B&S, upsell, or a ROB from an EROS ad.
Don't get me wrong. I have TOFTT and have been very lucky. However, after some years of experience, I am better at sniffing out the bad ones.

I would recommend that you stay with well reviewed providers for the time being. Later, you may wish to explore "new" providers or perhaps not.
It is amazing how many providers are "students" isn't it?  

Do a search here and you will find plenty of posts where veteran hobbyists strongly advise newbies to only see well-reviewed ladies.

In the past I have used Eros to identify ladies I might like to spend time with.  About 2/3 of them do not have any reviews on TER; so I move on to someone else who does.
