I forgot to check when the data was still easily available, but I think that RBNHole did not spot me during the following two activations:
a) Date:20/Mar/2017 Summit:HB/UR-042 (Badus/ Six Madun) Call Used:HB9/DK3IT/
Time ca. 12:25Z - 13:00 Z
b) Date:21/Jun/2017 Summit:OE/TI-358 (Patscherkofel) Call Used:OE/DK3IT/P
Time ca. 10:20Z - 11:44Z
In both cases, sooner or later a kind chaser did spot me, but I think there were additional spots on RBN that did not pass RBNhole, e.g. for additional frequencies I tried.
In case of a), the problem might have been that many skimmers are bad at skimming at low speeds (12 WPM or so), in particular for complicated callsigns (CEPT prefix and /P). In case of b), maybe the manual spot came to quick.
I just wanted to be certain that RBNHole does support prefixed callsigns.
Thanks for your effort!
