Sentence Correction (SC) | Re: QOTD: As criminal activity on the Internet becomes more and more

Hellodaagh ,

Isn't the highlighted part wrong? The three things in red are a list while the "and" after list depicts the second action of the thieves. Shouldn't the second "and" come without a comma?

We have a general structure in the following way:
I boughtpapaya,apples, and orangeand ate ice cream.

Please throw some light.
Regards
