I know there are a variety of screening practices used by landlords and property management companies.

I applaud your desire to expose the practices which created loss and financial hardship for so many.

How legit is their practice if you have an idea about it?

I believe transparency and integrity are the foundations of any good business, and it's refreshing to see others are aligned with that mindset and practice as well.
