Narrative:

PA31 airspace is comprised of alert area 292. Aircraft Y was squawking a beacon code that indicated aerobatic activity, but was not actually in the alert area. Aircraft X saw the aerobatic aircraft after I made a traffic call, but because of the aerobatic nature of aircraft Y, aircraft X had to take evasive action. I think these aerobatic aircraft should remain within the alert area. Callback conversation with reporter revealed the following information: reporter only added that the incident took place approximately 2 mi sse of jka airport and that this type of incident occurs often.

ACFT X SAW THE AEROBATIC ACFT AFTER I MADE A TFC CALL, BUT BECAUSE OF THE AEROBATIC NATURE OF ACFT Y, ACFT X HAD TO TAKE EVASIVE ACTION. I THINK THESE AEROBATIC ACFT SHOULD REMAIN WITHIN THE ALERT AREA.
