Here’s a tip on how to prevent getting scammed

Hi! Someone just tried to scam me, but I was quick enough to stop it
Some of you may already know this trick, but here’s what I did.
The moment you see the scammer run to the airport, exit to the home menu and CLOSE new horizons. This will cause a communication error. It worked for me and thankfully I still have my NMT ^^
Stay safe!

Keep in mind that sometimes scammers will leave by pressing the - button on the joycon and ending the session that way. Or if you go to their town they could also end the session to kick you out.

So another thing that you can do is to keep your inventory open once you drop your items that way they wont be able to end the session without dropping their own items. Or if you see the someone's leaving message pop up before you've gotten your stuff there is also a very small window of time you have to open your inventory to keep them from leaving.

What I have done to avoid scams for high tier items is require a video call. Doesn't have to be voice behind it but I do video calls with high end transactions to screen record the entire process. Especially buying / selling Villagers. I bought Raymond that way.

Most scammers will run once you make mention of those conditions because they know you're cautious. I weeded out so many by using that method.
