While the study authors recommend focusing on the content rather than the individuals posting it, it occurs to me that allowing
second-parties to index "about them" statements in StratML-enabled query services might be a premium, paid feature at
https://aboutthem.info/
That's just a wild thought at this point and nothing on which I intend to try to act anytime soon, but FYI for whatever it might be worth at some point in the future.
In the meantime, the Center for Growth and Opportunity's about statement is now included in the StratML collection and indexed in the query service.
