Our ads come to us from a third-party aggregator. We diligently maintain a blacklist of any advertisers that are not appropriate for children so that these companies will not appear on our site. If you or your students ever encounter an ad that you find inappropriate, please report it to us at support@ReadTheory.org along with the URL (web address) of the advertiser in question so that we can add it to our blacklist immediately.
Please note that we need the exact URL of the advertiser in order to block it. We regret that we cannot block advertisers based on keywords or categories alone.
