Correct, it's listed on https://webmasters.googleblog.com/2009/11/hard-facts-about-comment-spam.html for example (google's own blog). You really need to avoid doing that practice, and second, most of the blogs now only offer a "Nofollow" based website link (that is if they ever show a website adres within the template).

If you want to get links, a good start is to signup your website to category's / business listings that are relevant to your website or service you are providing. It might take a month or so to be found, caught up and see some changes going on. Buying links is a no go really, as that is to bypass a natural linkbuilding.

Good question! There's a few components here and I think we need to pick them all apart to give you a fair answer.

One thing is, as Jeroen mentions, it can take a while for links to get discovered, we can't expect immediate change.

Also, we need to bear in mind that DA is a Moz metric, it's not reflecting anything in Google. So we're not talking about how long it takes Google to find links, we're talking about how long it takes Moz to find links and, understandably, the Moz crawler isn't quite as prolific as the biggest search engine in the world so it could take a while. On this point, it's also worth bearing in mind that Moz DA will not affect rankings. DA is an attempt to estimate how important Google thinks a page is, rather than something Google directly considers in rankings. So in short - a higher DA might help us rank better but we can't assume that a higher DA will necessarily mean we rank better.

It sounds like you're generating links by posting comments on other sites. A lot of sites which allow comments automatically nofollow any external links. That's because historically people have tried to influence rankings by linking to external sites in comments. It can cause Google to think the linking site is spammy if all of the links are followed. By nofollowing the links, the sites protect themselves by saying to Google "ignore this link in terms of authority". That means that usually those links won't have an impact. Because DA is trying to approximate how Google thinks - DA will also ignore nofollowed links (as far as I'm aware).

Google is also less likely to pay attention to comment links because of those same tactics and if those sites don't automatically nofollow links then it's quite possible that Google's estimation of the value of that site is lower (and it's quite likely that DA follows suit but I don't know the inner workings of that calculation.

Essentially, I don't think it's terribly shocking that DA hasn't changed with this activity. However  - I'm also not sure this activity is what will help your business. If you're trying to improve your rankings I wouldn't leap to links first. I've given a more step-by-step process for how I would recommend you go about it in this blog post (apologies for the self plug but I think that's useful information and this comment is long enough as it is!)

10 days? Dude, it can take weeks months for the links to be found.
