Maybe they’re trying to DDoS it, and once an error is returned, they assume that no robots.txt file exists and then crawl everything else on the site?
While 7700 per hour sounds big, pretty much any dinky server can handle it. So I don't think it's a matter of DDoS. At this point it's just... odd behaviour.
