How about adding ToS clause to prevent abuse? wouldn't that be better than having a statement with negative effect on the rest of 95%?

That just gives your team another thing to do, trying to police a ToS clause. And one would have to define abuse somehow, which is quite tricky. There are a lot of guite legitimate but expensive ways to use such a general thing as LLM compute.
