Everything I write on my blog is NC. Realistically, this should be built into the metadata of the comments just like language as I’ve seen some folks get harassed for trying to license their online comments when this is an acceptable thing to do & a nice act of rebellion. Honestly I wish there was more room for things like the Peer Production License & Prosperity License for code to remove the commercial exploitation, but FSF labels in “unfree” & it’s GPL-incompatible so it is treated like cancer when really it’s like Creative Commons Noncommercial but for source code as it’s still allowed to be used by individual workers, nonprofits, etc.
