All of the following are ways to be admitted to a gang EXCEPT:

Being admitted to a gang typically involves certain established methods that reinforce the values and expectations of the group. Proving loyalty often includes demonstrating commitment to the gang's code or being tested through various means. Initiation rites are common practices where new members undergo specific challenges or rituals to prove their worthiness and allegiance.

Boxed in, in this context, refers to a method of forcing someone into a gang, which is not a voluntary admission or a traditional way of welcoming someone into the group. Community service, while beneficial, does not align with the typical practices associated with gang initiation or membership and does not usually form part of the gang culture's admission process. Thus, since it is not a consistent or recognized method for gang admission, it stands out as the exception among the other choices.
