You are not telling us anything about the business. What does it sell? Who are the customers? Are they repeat?
Read OP.If you don't understand, then it probably isn't the business for you, though I know I could school even the most ignorant person of how to run and maintain this. (even someone who doesn't read, though would be annoying..)
Pretty much runs itself.
I read it and it has SCAM written all over it! It's not like I don't have experience. I bought quite a lot of sites before from
https://flippa.com/But they always tell you the actual site name. Who the customers are, etc. You are showing screenshots without any specific information.
Which means either it's a scam, or it's doing something shady.
