Historically the gorilla has been portrayed as a vicious killer; however they are shy gentle creatures that would not attack humans unless provoked. In the wild their only predators are leopards, which can attack vulnerable youngsters and the biggest threat to gorillas is man. In recent decades gorilla populations have been affected by habitat loss, disease and poaching. Subsequently all gorilla species are classified as endangered. 

Silverbacks
Are large adult males with distinctive silver coloured hair on their back. This is developed through maturity and is usually present on male Gorilla’s over 12 years of age. An adult silverback can weigh over 180 kg and is the biggest and heaviest of all living primates. As the leader of the group the dominant silverback is in charge of protecting its troop from predators or rival silverbacks, displaying a broad chest and large canine teeth when threatened. The dominant silverback is also in charge of finding good places to forage for food and safe places to rest and sleep. If the dominant silverback dies then a troop will disband and form new groups.

In all the studies I have read there have been no references to attenton seeking, Silverbacks are not known for for being aggressive  but they are endangered through Disease and more importantly the impact of man acting unreasonably and being unprepared to share the planet with creatures who do not meet their own vision of perfection and acceptability. Bit like forums in a way. But that has been well documented already.
