Confusion about foreclosed properties VS REO properties!

[Alex R.]

There are some websites that list properties for sale as Foreclosure.

Meanwhile I read that:

Foreclosures are NOT sold by Realtors. Foreclosure properties are auctioned at a Trustee Sale at the Court House in the County where the property resides. Foreclosure properties must be paid for in full, with a cashiers check at the time of the auction

Aren’t they supposed to be auctioned off at a court house and not in a website?

Or are they actually REO properties that are mistakenly listed as foreclosure?

Here is an example:
