There should be something that indicates if the reviewer was shoved out the door before the paid time.

Also deductions for those who take calls and texts during. Some girls actually do that (and sometimes it is in the reviews). I turn my phone to silent and do not touch it at all during.

Maybe an icon for that specific review when the girl upsells.

... tend to get mentioned in review details, and many reviewers deduct point(s) for such behavior.

We could add all kinds of fields in reviews for different kinds of behavior.  Or we could just have a few and let the review text provide the details.  I prefer the latter approach vs adding more "flags".

Although for time, there is the "clock watcher" field.  That's not quite what you asked for, but when I see that someone isn't a clock watcher that gives me the idea that I probably won't be shoved out the door early... and I can verify that by reading her reviews.  

FWIW, I haven't been time-shorted or up-sold to for years, back before I'd learned how to properly research providers before seeing them. And the only time I can remember a provider returning a text during a session was when it came in on her civvy phone and it was something about her kids that she needed to respond to quickly.  

You do your research though. Whenever I check reviews (because of a post where a guy was complaining about bad experiences) seems to be a lot of girls who do those things, or even if I check when screening a guy. Are they TER gals (ie advertises here or posts here)? Most are not.  

It was just a thought. Maybe an icon on the provider's profile that says she has a handle linked to the account. Then guys know which ones are actively with TER. Can you even send pms off a provider profile if she hasn't claimed the profile?

...to her handle she can't send or receive PM's. The answer to your question is no.

... to get limited VIP, which includes PMs.  And then the "Send PM" button appears on the profile.  Since that button is there, maybe we don't need a new icon on the profile to indicate it's linked to the provider's handle?

Of course, another way for a provider to get PMing ability, without linking to her profile, is to pay for full VIP.  

If it is linked to a TER account. If the "send PM" is not there, then her profile is not linked.

That info should be in the text of the review. As it is a profile is set by the first reviewer and changed with problem reports. If your ideas were put in the profile it would result in things like:
 A provider replies to texts during her session by her first reviewer. So that shows up in her profile. She never does it again but her profile says it forever unless someone sends a problem report. Someone finally sends a problem report in, saying that she does not text during a date. Now no one knows she ever did that unless they read the first review text. Hmmm, isn't that the system we have now?

Like NYE, I have read those kinds of things in the text of reviews, but I haven't been shorted on time myself in many years. I have received the exact time paid for, many times. One hour if I paid for 1 hour. Two hours of I paid for 2, etc. I have no problem with that, and that is what I expect. I have also had providers who have gone over time or allowed me to stay over time or who have done OTC time after a date, etc. Just like Providers say about tips, my feeling about over time and OTC is "It is always appreciated but never expected."

As to the texting during the date, I recall one lady doing that back in 2013. Whole reading and replying to her texts she actually looked at me and said, "I'm sorry, this is so unprofessional." It was bothersome but I didn't say anything. Everything else about the session was so good that I actually saw her 4 more times. Guess what? She never did it in any of the following sessions.  

Now the problems you mentioned, as I said, I haven't run into those issues in years, and that is despite me seeing many what others would consider "low end" providers.
