Right on, yeah I think many of these are very valid. I wouldn't have thought people cared about black listing nodes but someone else I know suggested closing channels with nodes that show up as balance sharing node in their list. Unfortunately from what I can tell they have an option of balance sharing privately with just Amboss so you may not know that your channel partner is doing this.

If all else fails, and I don't use that term lightly, I think attacking these nodes are a very valid response to this.
