Reserve common subdomains

[ezekg]

class Account < ActiveRecord::Base
  RESERVED_SUBDOMAINS = %w[api app www help support doc docs documentation dashboard admin administrator root sales webmaster abuse monitor info blog git svn vcs files demo test dev develop development stage staging feeds ssh ssl secure sftp ftp mail webmail email pop pop3 imap smtp analytics stats status web]
  validates_exclusion_of :subdomain, :in => RESERVED_SUBDOMAINS, :message => 'is not allowed'
end

[ezekg]

Also might be easier to do something like,

validates_length_of :subdomain, minimum: 5

[ezekg]

And here's a crazy regex,
