I wonder if Google thinks it's extra suspicious if, in this case, a Swedish site has thousands of backlinks than international (English speaking) sites. Is there a bigger risk to scrapebox a Swedish site than an English site?
is the same risk. if you blast your fresh money site with a lot of spam backlinks....it's not so good for google. you can use scrapebox without problems for tier 1, tier 2
I dont know how old your domain is but personally I will not the blast the hell out of my money site but rather sites that link to my money sites.
Also don't forget about link velocity... If you want good rankings you need to maintain the "speed" of building backlinks ..so if you blast now like a mad...prepare yourself for the long job ahead
