Webfinger likes to give fully qualified names. For example: “acct:wilkie@rstat.us” We are going to relax this format and look up usernames whether or not the name starts with acct: and whether or not it ends with @domain |

This regex has essentially three parts: ([@\:]+\:)? = the optional prefix that ends with a colon ([@\:]*?) = the username (@[@\:]+)? = the optional domain that starts with an @ |
username = webfinger_name[/^([^@\:]+\:)?([^@\:]*?)(@[^@\:]+)?$/, 2] || webfinger_name
User.first :username => /^#{username}$/i
end
