I meeeeean, I already tried something like that with !vitahacksplus answering questions I thought to be interesting from Reddit, since my account from Reddit had been banned already and even if the OP didn't see the post as a reply, it'd be floating the internet at least. But at the time I had been trimming my RSS feeds and the ones for the Vita had too much fluff.

So I think it's valid, though I'd say it's best to not pretend you're the one making the questions.
