I built some web2.0 with content from webarchive. The sites were almost likely penalized and deindexed back then. I dont know that for sure but they have a spammy backlink profile and were obviously used for SEO purposes before. The web2.0 were indexed fast and even rank for some easy keywords. Would you use these web2.0 to link to your moneysite or is it risky because the content is somehow red-flagged because of the history? I heard that there is some kind of "historic google index".
