Even if there is hidden commercial activity going on, is that really so bad? Imagine if the internet banned commerce on it, there wouldn't be so much investment into it.
As for commercial activity, the whole point of the amateur spectrum is specifically to carve out portions of the spectrum protected from commercial interests! I agree that commercial, and also unlicensed use of radio is important, but leave commerce out of the tiny portion (and it really is small) part of the spectrum that's specifically regulated to be free of commercial interference.
I’d rather not have the ham bands reduced to more of the same.
Nothing stops spammers from spamming on HAM right now and it's 1 to many which makes it more effective.
Except the existing regulations, which is why spamming is relatively rare on Amateur radio.
Occasional infringement does occur, but it is relatively easy to track down and deal with.
And of course this is is the whole point of this thread.
