Pamela in Florida says:
As I am uploading some photos to the MLS for an associate this morning (I'm also an agent and photographer), I see this pop up for the first time - "...I hereby grant to MLO an irrevocable, perpetual, worldwide, non-exclusive, royalty-free, sublicensable, and transferable license to use, reproduce, modify, resize, adapt, prepare derivative works of, distribute, and display the images for any lawful purpose, and to modify, add to, or strip out the metadata contained within the Images..."
Yes, we've talked about this subject extensively in the past. Here is an example.
My non-legal assessment of the words you've included in your question (the above is just part of the MLS terms) is the MLS just stating their terms of service to clarify that when you upload to the MLS, you are granting them a license to use the photos for almost anything they want; just like the terms of service for Facebook, Twitter, and other social media sites.
Two things to remember are:
So the words from your MLS's terms of service don't appear to me to be out of line. They appear onerous but look up the Facebook terms of service--they aren't much different. If you think your MLS's TOS is out of line, I would suggest you consult Joel Rothman. Joel is an expert in these matters and has been involved in litigation against MLSs.
