Actually OP, you probably avoided the worst of it. With scams, having the foresight to only lose $1500 is a lot better than getting pilfered for everything.

In the future, realize that links sent over email are not secure. If you can get to a page through google, you probably should, and also obviously don't put bank account details into anything you didn't organize yourself.

If it makes you feel any better, scammers are usually miserable people, some of them actually wake up to that fact and flip the script on the business, there's actually a fair few content creators (especially in India) who were formerly working at scam centers and now try to expose the industry. Look up scam call vids, they're pretty fun to watch.
