Edited sentence: If the band is simply a post-hardcore band  with metal influence like Atreyu or Avenged sevenfold, it will be rejected as it is not metal enough.Most of the metalcore bands that are allowed are bands that are rooted in heavy metal but display hardcore or post-hardcore influence, like Trivium or Killswitch Engage.Recently, the deathcore band Bring me the Horizon was deleted from the archives, despite being rooted in heavy metal music.The reason is still unkown,but the act was not protested by the sites or moderators as Bring me the Horizon are commonly considered the worst metal band amongst music fans.The same rule applies to hardcore bands with metal influence such as Botch or Converge.This is becuase nu-metal and alternative metal are far more stylisticly rooted in rapcore and grunge music then it is metal, which it takes little influence from, thus it is rejected
