Why are banned players permitted to continue posting in this forum?
This makes no sense to me - it's essentially a half-ban, especially if that agent continues to be disruptive and cause drama.
Are they banned from just the game? If I got banned tomorrow, I would be allowed to post here as much as I want?
It can't be for ban appeals - that's what the support site is for. They're not permitted to chat in comms, but they can mention people in threads in the forum as much as they want. In what way is someone with a permanently terminated account part of the community?
This seems incongruous, and like a gap in your policy.
Please review it - otherwise, it sends the wrong message, and means that account bans are not as effective as they ought to be.
