Definitely. I look forward to the measure / counter-measure fight.

... but this is the same company that currently owns the top-tier solution for ad spam and ad fraud; I expect them to be slightly harder to defeat than Twitch.

I see comment spam in every major youtube video I see. As long as its not a top level comment, it doesn't seem to stop any spam at all.

Whatever their spam product is they're either not using it in youtube, or it doesn't work.
