Can I filter X-Day old accounts as they're likely bots or trolls? - eviltoast

Pretty much the title: I see multiple posts on 3-day old accounts, all promoting disinfo for the RUS, ISR, CHI or some weirdo faction thereof. CanI set a filter on my account to ignore these prolific bastards until they have attained certain age or number of responses that exceed the AI 's smarmy word count?
