If you’re selling through a platform, don’t trust anyone who wants you to do the deal on another one, under the pretext that they have balance there or that it’s “safer.”
The person’s intention in taking you to another platform is that there they already have the fake email layout they want to send you.
My tip is: as soon as the person asks for your email, walk away. The platform already has that information.
Another tip is to accept payments only in cash or via Pix.
And be very careful when making shipments. The best thing is to hand it over in person, directly to the buyer.
