Having listened to a few hours of Zuckerberg's testimony on Capital Hill to defend Facebook's involvement in the disclosure of data about 30 million users and improper secondary usage of that data to influence election results, I am wondering if we could face a similar issue as forum administrators. It seems to me that there are some plugins such as Tapatalk, push notifications and some search engines such as Treadloom that have access to some personal information related to our forum users. What if they used that information improperly? Do they use that information to target advertisements? Do we face such a risk?
