You make a good argument. To me it still feels like you can "effectively" censor something by flooding its channel with crap. Maybe there is a technical way to filter away the the "noise", but it's unlikely that the audience will bother. If you DNS-block a site is that still not censorship, because you can still reach the site by IP (if you can find it out)? I'm genuinely asking here, I think this is an interesting case and I'm not able to make my mind up.
