i am loosing my web 2.0 lists very fast

In January 2012, i have nearly 700 web 2.0 lists where i can post blogs.

now that lists reduced to 140 only. I tried very hard to find new web 2.0 websites, where i can post blogs. But not getting good success.

Maximum web 2.0 website closed their door for new registration, or they deleting blog post in 1-2 days or they are not allowing blog posts.

Is any one have good web 2.0 lists where i can post blogs.

I am using 70-90% unique spun contents.
