Forums are usually pseudonymous because the format lends itself to more vulnerability, so most of us opt for pseudonymity. Status/identity are also relatively unimportant in forums because ideas contend more than personalities/lifestyles/brands/larps do. Also, bitcoin is controversial and it's relatively dangerous to broadcast that you own bitcoin.

SN considers privacy a core value for these reasons (and it's a value we can uniquely provide given that SN is a paid service) so we do things like not storing email addresses associated with accounts in plaintext, provide real deletes, allow you to delete your withdrawal invoices, (try) to provide a working onion address, allow commenting and posting without an account, etc.
