Expired weebly blogs

How can I find targeted expired weebly blogs? Like if I want to find expired weebly blogs in soccer niche?

This is a great question. I also wonder if there is any mechanism to find expired weebly blogs as these sometimes rank in various niches.

The same way we scrape Tumblr, I found too less Weebly blogs as compared to Tumblr blogs

any use for the expired blog account, no offense

You visit the marketplace and you look for my sells thread.

Getting niche targeted expired blogs is hard. It depends on niche. Think about it. All this expired blogs that you can register are deleted by their owners. So you might understand that there aren't many SEOed blogs deleted willingly by their owner.
It's not impossible but most niches (especially specific ones) will be rare. Go for it and see what you get.
