facebook 'related discussions' problem

[ardent]

I don't like facebook but there are some things there that are helpful like the Groups you can set up for special interests and I have several of those. But all of a sudden facebook has introduced this horrible thing called 'related discussions' where suddenly you get someone else's posts tacked on to your own posts without permission. Not even vaguely related in content either. Totally infuriating. I did some google searches to try to find the settings that turn off this unwanted feature and none of the suggestions worked. So I'm wondering if anyone here has experienced this and has found a solution.
