By the way, I hardly ever check my "top news" -- only "Most Recent" -- but I did check it this morning and I see a lot of this sort of thing -- where friends have commented on a link from someone else (on groups or pages which I'm not a member of). It only seems to happen with links and photos, though -- not with straightforward posts.

But, group or not, is there some way to prevent comments you've made on a link or photo (which you did not generate) from showing up period?
