I have zero generic social media. Couple flying and car and weapons forums. Two philosophy forums. No myspace, twit, FB, insta, linkin, etc. From that perspective, I completely agree with the ban when "professionally engaged" in their job for BA. Some cabin crew from other airlines seem to become obssessed with their phones and PDAs. I've seen cabin crew sitting in the galley, on their phones uploading, downloading, chatting, posting, and sharing while they are supposed to be working. Enough. I don't think it's asking too much that one work during their work shift and that does not include social media.
