This person sells cracked not updated download tools to crack DRM protection from major streaming services.
When you first pay that person you will get links to download the tools you bought but it won't let you know they are old.
You will be asked to pay again about half the money you paid give more take less so you will get update files for less than 1 (one) month.
When that month passes you will notice the last message you received was 2 weeks old or even more, if you message that person regarding any updates you'll get a negative response.
Within 24 hours or less you will get another reply regarding more money to get updated files. 
This is basically a ponzi / scam scheme.
