How to do background checks on someone for arranged marriage?

I almost got saved from having my a$$ married off to the wrong person. My father set a meeting with a guy's family this week. I saw the guy's profile. It seemed fine. My father was too enthusiastic (he was rich you know). But my gut was telling me something is wrong. There is another story here. I searched on facebook his profile seemed like he wiped out a lot of stuff. I got suspicious. Then after some digging I came across a picture of him with a friend of mine. They were mutual. So I knocked my friend to get more information.

And the information I got was jaw dropping. That guy was married before back in 2023. Then he was divorced after 6 months of marriage. Not only that he used to have a crush on my friend and tried to pursue her but she rejected him. So at one point he used to send her anonymous messages and harassed her. This harassment continued even after he was married. My friend blocked him. And tbh after more digging I came to know he was a spoilt brat. He would show off his things and stuff a lot and has a narcissistic personality. Look I know I shouldn't judge someone just because they are divorced. But I don't feel comfortable marrying a divorced guy when I wasn't even married once. Maybe if I was divorced too.

But still I was ready to give him benefit of the doubt. Because people get divorced for many more valid reasons. Though I would've been extra cautious. But after hearing his history of harassing I was like NOPEEEEE!!!!. I got lucky because I had a mutual friend with him but I know next time I will not be lucky. Arranged marriage is like that. You never know who you are marrying. So how can I get a background check done in case I do not have mutual with someone?
