Aircraft X was cleared for a practice approach into 06A.  After Aircraft X departed and was identified; he notified me that they were putting yellow X's on the runway and that the airport appeared to be closing; at which point I notified Management. We were not aware of the NOTAM and the pilot also mentioned that he was not aware of a closure NOTAM at 06A.  While Management was looking into the situation; the FD Controller came over and told me ZTL FD had just called in an airport closure at 06A. Maybe the airport should call the facility directly when they're going to close an airport on short notice.
Aircraft X was cleared for a practice approach to 06A.  On missed approach; Aircraft X reported that there were yellow x's placed on the runway.  There was a NOTAM issued closing RWY 13/31.  The facility was not notified of the NOTAM.  Aircraft X did not land on the runway; but did execute a low approach.  Aircraft X also stated that they did not see a NOTAM closing the RWY prior to their initial departure.  Change how NOTAM's are issued for airports.  This is unacceptable.
Atlanta TRACON Controllers reported that a departing aircraft advised someone was putting yellow X's on the runway as they departed.
