If a member is restricted in something they can do in the community, they will be formally notified via a private message (PM). You do not get privileges revoked here for no reason or with no notification.

Our logs show that you accessed the chat rooms last night, so apparently you found a fix for the problem you were experiencing?

Members can only kick out other members from their own personally-created chat rooms in chat. Only a member of the community team -- a moderator or administrator -- can ban a person from the chat system altogether. And they would never do that without notification and discussion amongst the entire team.

You are a member in good standing and there's no indication of any issues on our side, so you may want to review the technical support forum here, searching on chat, and see if any of those solutions work for you. The first thing you should try if this problem persists is to try the "No Popup Chat" option in the Chat menu at the top of the screen.
