I'm not sure if there was a lot of aloha there to begin with. That's the flip side of the coin. There certainly areas to avoid like anywhere. You can buy an acre of land over there for 10k for a few reasons. One of those is the fact you would live on an active volcano. It's certainly the poorest area of our island.
Edited to add: Might be better to just avoid Pahoa all together. There were only a few really great things to see over there but Pele decided she didn't want those around anymore. Just like Katrina there was a lot of similar talk that she did it to purge the nefarious people from the island.
