Some web 2.0 problems there

Hello,

I am scraping for web 2.0 as fuck and I find many accounts but when it comes to check on availability I only get tumblr accounts to register. Do I do something wrong or is tumblr the only shit which is free?

So I have to register wordpress and other blogs on myself to push them? Should I take them like Tier 1 or should I do them to push Tier 1 Links?

Thanks for your info and all the guys which help me every time with my questioning!

tier 1 for low comp words. I think other web 2.0 websites basically never expire
