Exchange Links - Problem or Not ?

[imoveiscamposdojordao]

There's a company that sells a real estate portal sites ready for several companies.
And when they install this system they always leave each site in a file calledimobiliarias.php that lists all properties that use your system, so there is a hugeexchange of links between the same sites.
So you can see with the Open Site Explorer that all sites have the same Backlinks.
This would not cause problems with regard to exchange links?
Loss of position or something?

Thank you guys.!

Sorry. Google Translator.

Thank goodness it no longer works now, Penguin and Panda are crushing these schemes.

These are quite common with auto submission/ Link building software organizations as well.

Run!

I'm with Mr Weiss on this one. It's dodgy.

"there is a huge exchange of links between the same sites"

that's called a link farm - stay away or you'll be begging for a penalty. Look at the sites that are currently listed on there and see if they are penalized / rankings suppressed.
