Is this user an undocumented member of staff, moderator, bot or user? If this account belongs to a regular user would the username violate the TOS for impersonation?
This account was created for a "special project" to create an experimental election coverage site. The exact methodology behind how we'll execute these special projects is still largely experimental, but I agree that the "Stack Exchange" user seems a bit out of place. Thanks for pointing that out. This is just one of those areas that still needs a bit of work.
