TPU will be nearly impossible for your kiddo to destroy. ASA/ABS are rugged, but if your print has thin surfaces it’s less strong in my experience than PETG.

I didn’t find TPU hard to print personally, just go slow and turn retraction way down or completely off. It will string pretty good, but most slicers have a setting to avoid crossing perimeters that will keep it in check. The only thing I would be wary of is ending up with a floppy print, so make sure the part has some structure.

I don’t see that being worth much $$ given the massive quantities of that information already available on the web via forums and what not?

Lots of very general light chat and shit posts. It doesn’t seem like there’s a lot of revenue potential there.

Why would you block a whole instance if you don’t like the actions in just one of its communities?
