I post nearly nothing on Facebook and am not an activist, and I've been getting the same kind of emails very frequently lately. Some (but not all) of my friends have reported the same. It's likely that it's just random phishing spam.
Edit: To be more specific, the emails use the names of my Facebook friends, but have incorrect sender addresses, indicating that they're just spoofing the name rather than hacking the email accounts of my friends. They're usually fairly short, with an obvious phishing link to a gibberish domain. They come from Facebook friends that I don't necessarily communicate with, and I've confirmed with at least two of those friends that their accounts have not been hacked.
