When trying to suggest new edit, I saw this message:
You are temporarily banned from suggesting edits - please review your edit history
I reviewed my history, but found no recent rejected edits, so it probably means a moderator manually banned me from suggesting edits. Hence, I can't know when it started and when it will be over.
I would like to see for how long I am still banned, same way we can for example see for how long we are suspended.
