If they're extorting to locals for resources , they're effectively just bandits who can increase their numbers quickly and efficiently.
If they need to kidnap women of other races to do so, they're even more likely to get targeted.
Basically they could only avoid being targeted if they're self-sustaining, keep their numbers small enough to not pose a threat or large enough so that trying to get rid of them without them actually provoking anyone would cause more casualties than leaving them alone or if they're very sentient and can be traded with or diplomacy works with them.
Any of those happen, they wouldn't be targeted for a majority of reasons, until human supremacists or someone who had suffered on the hands of other orcs comes along, then they're out of luck even if they had done all of them.
