It's true, although many of the algorithms will by nature not emphasize popular items. There is an old and semi-deprecated class in the project called InverseUserFrequency, which you can use to manually de-emphasize popular items internally. I wouldn't really recommend it.
You can always use IDRescorer yes. If you have business rules that dictate some things must be filtered, that's the right way to go. As purely a tool to demote popular items.. it's a bit heavy-handed and not the ideal way to solve it.
