Links from PA/DA of 1

[HashtagHustler]

My immediate thought is that a link from a website that has a PA/DA of 1 for both or either metric would be absolutely worthless, but I just wanted to make sure.

Could this also be from it being recently indexed?

Also is there a rule of thumb that anybody knows, or tries to follow at least? Obliviously the higher the better, but for example;

• A PA/DA of 15 and below is SPAM
• A PA/DA of 30 and above is GOOD
• A PA/DA of 50 is GREAT
• PA/DA of 80 is AMAZING
• PA/DA of 100 is GODTIER

That still has value. Think Wiki. I bet they have a gazillion links from sites with no DA and pages on those sites with no PA. (1 is lowest so no value theoretically). The fact people are linking says, there must be something here. 
You are confusing fighting link manipulation with what links are intended to do. When I answer a question on Moz and link to a specific piece of knowledge, there is typically a nofollow which would mean the link is less than 1 in value. But, it is not lacking value. The fact someone is citing a piece of content has intrinsic value.

Also, there is not black and white in SEO. Everything has uses and misuses.

Frankly, I do SEO and I don't wear hats.

What if the site has a PA/DA of 1 on both metrics?

Hashtag,

I think you are looking at this in a way that is less than helpful for you. I can show you a ton of PA/DA links that are less than 16 on both and are absolutely not spam. They are also useful links. If you put up a page and over the course of a month, you start to get links and they are from sites that have PA/DA of lower values and the number linking to you increases by doubling every two days, I am guessing you will rise fairly quickly in the rankings for most verticals. Why?
Because your link velocity is increasing but it is not that today you had two links and tomorrow you had 1000. It is happening over time the same way it does when a news article is shared or a video goes viral. There is a gradual uptake that begins to crescendo. Not Unnatural. 
Links are not placed for the purpose of sharing "juice." Links provide a mechanism to give additional information(value) to a written piece of content. On an eCommerce site you may have a link from a product description on Amazon to a detailed one on the producer site. On a site that is explaining why Led Zeppelin is one of the greatest rock groups in history, you might have a link to Wikipedia. That does not mean if you are Wikipedia the link is bad. That is precisely how Wiki became the greatest knowledge resource in history (at least the history we know of). 
Hope it helps,

Robert
