[Ind] Art commision paypal scam?

So I make art and i got a request for a commision.

I shared the art as 50$ was decided as the commission amount.

They said they'd pay me using PayPal, the shared a screenshot of payment, it didn't have details of their account, just a green check mark and 50$ credited.

Then I checked spam email and I got an email which says I must ask the person to transfer 300$ to my account to increase the limit and then my account limit would increase and then I must pay them back. (Seemed weird to me)

The tone of the person in Tumblr DM became rude, they demanded their money back? But i didn't even receive the payment lol, I sensed it was a scam

The person said they'll get me arrested and complain to police, i checked the email and it had .co.1 before it ended, I called them out saying that I sense a scam.

Now that account blocked me on Tumblr
