A number of ladies have said to make a list of ladies you’d like to meet and save their info. What’s the proper etiquette for this? Aside from the usual, introduce yourself, share contact and screening info, what else should we do? Should we mention that we’re doing this in the context of FOSTA/SESTA in order to appropriately set expectations that we’re not looking for a meeting this week or month? I want to balance appropriately reaching out while not wasting your time.

It is common practice to ask for "pre-screening" for the possibility of a future date.  I - for one - have never considered it a waste of time, or problematic for any other reason.

A lot of folks are seeing their ad boards disappear, so they'll understand  the context. I think that's a good way to balance it. Good luck with your list!

Great post. I think the best you can do for now is save the info of some providers you’d like to see. Providers also giving referrals is helpful too. Make sure to change your email to an encrypted account as well everyone.

Why not just use the My Favorites feature right here on TER?

Hobbyists trying to submit reviews in the last 48 hours are seeing them rejected because of no ad link.  My Favorites is a good tool for now, but things are changing on a daily basis.  Maintaining a personal list of providers you’ve established direct contact with seems the way to go for now.

I sincerely doubt that anybody will deem you a time-waster xo

Part of it is planning for a possibility where TER or P411 go down.

I would advise for you to make a list of the ladies you want to meet in the near future and contact them asap.
This way, you will be in their 'radar' as a possible future date in case some go UTR and be exclusive companions to few lucky gentlemen.
Our business model is going to change, real fast. New ways to keep contact with each other and new kind of terminology to name what we will portrait ourselves so you can still find us online.  
Social Companion or Dinner Date searches ? yes!  
Escort searches? RIP

Because worst case scenario: the site goes down entirely.

Given the situation, no one will think you’re a time waster! I’m certainly seeing an increase in pre-screening requests, which I’m totally fine with. We know so much is up in the air right now. Just reach out to the women you may want to see so they have your contact info. I can’t speak for everyone, but I’m not keeping a list of people who are reaching out now to track them down later and make sure they book I know they’re interested, but that may not translate into a booking down the road. Given the current situation, that doesn’t feel like a waste of time to me.  

I’d just say you’d like to be pre-screened for the possibility of a future date.  

P411, PM on TER, if you switch email, communicate your providers before.
