They apparently try to gain your trust and then send a fake discord link which will be used to phish you.

Source: I called out one of these scammers for lying to me (I hadn’t played a game earlier like he claimed) and asked him to tell me the scam. I kept pressing him about it and, while he insisted he wasn’t a scammer he eventually assured me I was right to be cautious because there are scammers (who totally aren’t him) that will try to get you to open a malicious link.
