The bulk update request #12334 is pending approval.
create alias octothorp (0) -> number_sign (151)
create alias octothorpe (0) -> number_sign (151)
create alias hash_sign (0) -> number_sign (151)
create alias hash_symbol (0) -> number_sign (151)
create alias hash_tag (0) -> hashtag (784)
create implication hashtag (784) -> number_sign (151)
Reason: According to wikipedia the name chosen by the unicode consortium is "number sign", so that seems like a good enough of a name for us to use
While octothorpe is the technical name no one's going to know what that is, and I will explode if we keep it as hashtag
We also can't alias pound sign because it's used for the currency (is that worth a disambiguation?)
