Given the Hirogen's nomadic society, it's likely that while the Borg assimilate any stray Hirogen they run into, they're not worth the effort it work take to assimilate the Hirogen as a culture - they're simply too dispersed.Monroe wrote:Voth, Hirogen, and many other Delta races live right next to the borg but seem unworried about them.Teaos wrote: I'll also point out that Starfleet is one of only 2 species to ever soundly win against the Borg the other being 8472. You may call the Borg incompetent but in canon they rule a large chunk of the universe and no one seems to be able to stop them.
As for the Voth their ships are a dozen kilometres long and they're proficient computer hackers. It's probable that it that case the Borg are simply outmatched.
