I performed a fresh install on N9JR-4 and I observed the following.
Without logging in, I was seeing RBN spots.
After logging in but with RBN disabled for user N9JR-10 I continued to receive RBN spots. My filter settings are as follows:
Filters for N9JR-10
[rbn]
accept/rbn 1 call N9JR
[spots]
accept/spots 1 by_zone 3,4,5
After enabling RBN my RBN filters were not being applied,
I did notice that I was seeing a FT-8 RBN spot.

BUT, RBN spots for FT8 are not enabled at the node level.
