Those links you get from Whois pages etc are quite worthless. Well those backlinks use for certain things not as links for your websites. As for your websites, mass linking doesn't work anymore long term. When I say mass linking it goes for signature links. Wordpress or website footer links etc. But there are ways you can use irrelevant links for your sites. That's by getting links from those big brand domains. It doesn't matter these are do-follow or no-follow and you only need just one single link from each big brand domain name. As individual links these won't give you much but as a whole it will make an impact on your Domain's Authority. For example you can get a Google.com from Google support forum. or from Twitter from your Twitter profile link. Few other places are,

01. Yahoo Answers
02. Quora
03. Youtube
04. Instagram

etc. Some of these you get as dofollow and some you get as nofollow. Also Sites like Twitter redirect all links. No need to worry about these things since link juice is not the idea here. What you do is increase either your domain authority (DA) or page authority (PA).
