So I've stumbled upon a method to register Twitter accounts that have expired or their previous owner changed @ name. After reading Leith's guide I was gassed out about Twitter and definitely wanted to start scraping ASAP. Now I have around 5 Twitters all above 20 TF and some with 50+ RD. So: how useful are these? All outgoing links on Twitter are indeed nofollow (if you're logged in they are followed, weird enough). What positive qualities do nofollow links have if they don't pass link juice? Is it worth continuing to register 100 Twitter accounts which was my original goal to rank my authority site, or should I stop and focus my efforts on PBN domains and follow-only properties? Cheers.
