# Authorized Digital Sellers (IAB ads.txt) for linguardia.com
#
# Declares who is allowed to sell ad inventory on this domain. Programmatic
# buyers fetch https://linguardia.com/ads.txt and refuse bids from any seller
# not listed here, so this file is both the anti-spoofing measure and, for
# AdSense, the site-verification method that costs the page nothing: it is a
# static text file, so unlike the <script> snippet it loads no third-party
# JavaScript, sets no cookies, and cannot slow a lesson down.
#
# Fields: <exchange domain>, <publisher id>, <DIRECT|RESELLER>, <TAG-ID>
# The last field is Google's own certification id and is the same for every
# AdSense publisher.
