Given how many comments I receive in the vein of "are you seriously licensing your comment?", I think the intent is quite clear. But since people keep asking why, I might add a blurb (since I don't have a page I can link to) to explain that.
You are free to improve on the format if you like. Maybe I'll see a comment of yours with a format I agree with and copy that formatting.
I think the fact that you got the point from the license name and the link fulfilled the purpose of informing the reader.
As for AI training who knows how well they clean their data. Copilot spit out the entire GPL verbatim as well as a few other licenses and got sued. Data cleaning processes clearly vary among companies.
But if you have an idea on how to better indicate that content is licensed at a glance, go ahead and do it.
I've tried multiple things to try and help people understand why I paste that there. This is the closest I got with the least amount of comments about it.
A single folder and power consumption is important --> syncthing. It doesn't have great power consumption, but since the devices aren't constantly on, you can just start syncthing up on the portable devices when needed. You can configure syncthing to sync when connecting to a specific Wifi, when power saving mode is turned off, I think even specific times.
It'll run fine on a server and can be configured .
