Finding old removed blog accounts

I have tried tumblr, bloger, and livejournal.

I have my huge list of keywords in scrapebox and i do a mergefile with site:tumblr.com , blogspot, livejournal, etc...

I created a list of about 100k account.

I went to the alive check and set the options to 200, 301, and 308.

Checked them and got about 150 accounts that no longer existed.

Does anybody else have luck trying to re-register them? Every one i have tried over the past 3 days comes back and says that its already registered even though its not active. I know blogspot wont work because it flat out tells you it does not exist and you cant re-register it.

I figure you would never be able to do anything with them. Usually people don't voluntarily have an account removed... they just let it sit and rot. If they aren't rotting then they are banned

I know Blogger has a 6 month grace period. So a user deletes a blog but you can't grab it until the time lapses.

If you're hardcore, then create a scraper that checks daily for when they're available.
