New US visa rules will force foreign students to unlock social media profiles

I don’t use social media. Is the assumption that everyone does use social media?

You’ve been posting here for nearly 10 years.

I don’t consider an anonymous link aggregator with a forum bolted on top to be social media. To the best of my knowledge I’ve never read a comment from the same person (assuming they are people and not bots) in more than one post. Strangers passing in a pitch black room a single time is hardly social.
