Backlinks from Top List Websites?

I've been noticing backlinks from websites that have the same design but with different domain names. They seem to be a web directory of the top 1,000,000 sites online. Should I be concerned?

you get these links when buying some expired domains, these are kind of directories that maintain a catalog of all the domains expiring that particular day.

Our site is listed and is no where near expiring though. They have a blatant buy backlinks link on their sidebar as well.

Any advice is appreciated, I'm on the fence with disavowing these links. I haven't noticed any negative effects from them as of yet.
