Voted again, but the site has been refusing my google log-in for the past couple of days. Had to vote with an alternate.
Just got an apologetic email message pointing out the fact that participants' email addresses were accidentally revealed to all participants. The sender didn't put the addresses into the B.C.C field, so all recipients can see the other recipients' addresses.
The chances that at least one recipient has email-harvesting spyware or compromised account credentials is practically 100%. You'll probably get some spam you wouldn't have gotten otherwise.
