Yeah, sorry, I really meant "write" not saying "ето", I just realized that for some stupid reason, "say" can mean communication of any form, even writing. I think what made me think people were using genitive on inanimate nouns in the accusative, might have been the word города, which I thought was genitive, rather than plural nom.. Also, sentences like "Он чего писал?" make me think that что is mistakenly is the accusative-animate, since phrasings like "He wrote of what?" are nonexistent in English. My mistake
