Each to his own. The point was that a considerate operator would leave those frequencies clear unless there is nowhere else to transmit. Those frequencies have been singled out on the bandplan for decades. The point is not to support automated stations, but rather to keep the frequency clear for its designated use. Of course nothing is an allocation. You could go down in the CW portion of the band and talk if you want, but that would be rude and you would get a lot of complaints. A considerate operate would not do that either. I think the SSTV frequencies should be down around the digital frequencies, but they pre-date so much of that stuff. The fact that the SSTV frequencies are in the SSB portion does not help anything. I think most people who transmit there don't even know the significance of the frequency. I am not going to say I have never done that by mistake.
