ChanServ:SET:KEEPTOPIC
SET KEEPTOPIC enables restoration of the old topic after the channel has become empty. In some cases, it may revert topic changes after netsplits or services outages, so it is not recommended to turn this on if your channel tends to never empty.
Syntax: SET <#channel> KEEPTOPIC ON|OFF
Example:
/msg ChanServ SET #foo KEEPTOPIC ON
