The Tezos proposal just recently entered private beta. Supposedly, users have to commit to the proposal to participate during the private beta. However, I tried posting on Tezos using an account on which I hadn't committed to the proposal, yet I was still able to post an answer! (check here if you don't believe the account wasn't committed)
Is this intentional and there has been some change to allow non-committed users to participate in the private beta, or is this a bug?
