TL;DR: It's clear that when you're trying to pick a woman for an LTR or Marriage making sure she isn't a former whore/slut is very important. What are some of the subtle "tells" she'll give off if she has a slutty background?

Good article here from Rollo's blog on how to "vet" a worthy woman for an LTR or marriage.

I've quoted few of the more intriguing paragraphs from the article below, especially what's in the third paragraph.

"However, we weren’t discussing non-exclusive dating/****ing; we’re discussing making an investment in a woman we’re vetting for our own parental investment. When you consider the all-downside risks a man must wager on that investment it behooves him to be his most particular about that woman’s sexual past and the consequences that YOU will be burdened with if you don’t vet wisely.

So, now that we understand the latent purpose of this social convention, let me explain to every gentleman reading – vetting a woman’s sexual past is not just your prerogative, but an absolute imperative to the health of any future relationship you hope to have with her. When you consider the dire risks you are essentially setting yourself up for – risk no woman will EVER acknowledge or appreciate – the single most important thing you can do is vet that woman’s sexual past.

That doesn’t mean you make weak, DLV, overt inquiries about her past. It means you subtly, covertly and discretely pick up on the many cues and tells she will reveal that past with. Most men would rather use a direct approach to this, and while there’s merit to that, it’s far better to do your vetting by drawing out freely offered information. It’s much more honest and reliable. Once you go the direct route the jig is up and she will play the role she thinks you expect from her, not the honest one you need to make your determinations."

So my question is:

So for you guys that have been around a while, what are some of the subtle clues or tells that a woman with a high partner count or overly slutty past will give off during the course of a relationship that let you know she's not LTR or Wife material? I'm looking for things that most guys wouldn't notice, i.e. not that she really seems to know what she's doing in bed or she openly talks about all her former lovers. I'm looking for things that a woman who is really trying to hide her past from her man would convey subconsciously through her mannerisms, actions and behaviors over time.
