How do they ensure the data is updated daily or weekly if they get from county websites and the bulk data they get from these county/notices and court websites is it like a web scraper?

It will not be soon, but the web updates optimized for mobile will be soon.

I’ve only found one article about them and I don’t know if I can put a link on here or not if I can’t I will.It is my understanding that they crawl the web and demand blackmail money over images that they claim is in violation to copyright.

I run a web development team and still code in web and mobile.

Go to IL REIA web site and register.

No but navigation of forums in app easier than doing it on mobile web 

Additionally apps are more accessible and faster because some people’s phones take too long to load web pages and they get impatient.

The TLDR version of that web page and other related web pages is that, in Arizona, if you start a foreclosure action against a homeowner who has equity of more than $2,500 in his house using a tax lien certificate, the "defendant" can ask for excess proceeds during the foreclosure action.

If you have any specific go / no-go criteria, you can evaluate it on the web most likely. 

I signed up for something on Ron LeGrand's web-site (the free access portion).
