[exchange] Deleted tumblr, blogspot, weebly blogs with PR=1-3 for backlink on your website

If you can give me permanent backlink on your website (in brogroll or in other place, but must be on front page) i can give you free deleted blog (tumblr, weebly, blogspot) with PR=1-3, first people will get higher PR, pm me if you are interested
