I'm assuming that the misleading message is because of my assumption in my scenario (user is banned somehow).

And therefor the message should rather be something like " ... - no more edits are allowed" (pick whatever fits to replace the '... -' suffix I suggested here.

Maybe add some extra indication like "because your userid has been banned" (or some variation of that). Better still: include the applicable values for **rejects** and **approvals** indicators mentioned in one of the answers in http://meta.stackexchange.com/questions/91392, which says:

> When deciding on whether we should ban or not, we now look at your last 7 days of activity. If (rejects - (approvals / 3)) >= 5, you will be auto-banned.
