Google does not like links from obvious sources of spam.
Google does not like links from untrustworthy places.
Google does not like "dofollow" links created solely for the purpose of boosting ranking (if they can tell they were created solely for that purpose).
Google does not like paid "dofollow" links (links that flow PageRank) if they can tell or suspect that they were paid links.

It's theory, I'd like to know how to define or which places are considered as sources of spam or untrustworthy places?

I don't know how Google can determine a link is paid or how can they suspect it?

For the most part...

Stay away from article directories, profile links (a handful are fine, but don't start building them in large numbers), blog comment links, forum links, spammy press release links, massive amounts of web 2.0 links, public blog networks (if they advertise, then they are public no matter how many times they use the word 'private'), and anything sold on Fiverr.

If you do that, you will probably be fine.

It is tough to come up with a strict definition of spam because as soon as you define it, someone can show you an exception to the rule. But, it is easy to spot. You know it when you see it. So look at the pages and websites you would be getting links from. If they look spammy at all, then you don't want links from there. They might still work, but they might also get you in trouble one day.

For the most part, in regards to linking practices on the web, Spam = a website or web page that links out to multiple (obviously) unrelated pages that are not useful for the visitor in any meaningful way. It would also include any page/website that had content on it that is completely worthless to any visitor (such as spun content or scraped content)

I don't know how Google can determine a link is paid or how can they suspect it?

They can't tell if a link is paid or not unless the person advertises that they are selling paid links or unless the link is made to look paid. Again, it is something you know when you see it.

Imagine you have a popular website about puppies and your homepage has achieved a PageRank 6 rating. In the sidebar of your puppy website you have a small stack of links where one link points to a limousine company, another points to a landscaping company and another one points to a chiropractor. Those links look like obvious paid links. They look like they are there to pass PageRank and boost the rankings of those websites they link out to.

The vast majority of paid links are undetectable to Google unless they are part of a link network of some kind. Even then, they are still sometimes hard for Google to detect. It depends on a lot of factors.

spam,non niche and black hat created backlinks google always hate them

Spam, using black hat SEO, using bots to build links, too much backlinks in a short time, fake reviews etc. if you want to rank in google i recommend quality content + limited but perfect SEO.

Look learn what you need to know about SEO. Links are usually bad because of the way they are used and not necessarily the link itself.

For instance, links from porn sites are bad if youre not linking to a porn site.

Web directories and public blogging networks are bad. Private PBN sellers are Ok depending on the source. I deal with my source personally and still check the quality of his PBNs. Content, OBL, Trust flow, and domain authority are the main things I pay attention to.

Also mobile friendliness now a days. If you have a bunch of links on sites that aren't mobile friendly, this could cause a problem after the latest panda filter and phantom update that had to do with h1 ending up directly above an image. This is an over optimization problem.

Honestly, I could go on forever about the do's and dont's and 3 months from now it would change. Do yourself a favor and spend 2 hours everyday reading credible SEO sources that tell the real deal.

Oooo he doesn't like a lot of links:
Directories without content
Not indexed websites - Any kind
Not relevant website to your niche(your link must have a connection to your niche)
Websites that were built only for SEO - no real use for user

These are a few of the options you can read more in Matt Cutts blog or Google webmaster blog
