How does a Self-XSS scam work?

A Self-XSS scam usually works by promising to help you hack somebody else's account. Instead of giving you access to someone else’s account, the scammer tricks you into running malicious code that gives them the ability to use your account for fraud, spam and tricking more people into the scam.

To avoid Self-XSS attacks, never copy and paste suspicious links.
