Narrative:
Climbing through about 8;000 ft. ATC advised us of VFR traffic at our 1 o'clock; around 3 miles away. It was maneuvering erratically. I immediately saw it. It was performing aerobatic maneuvers. It seemed to me to be rapidly coming towards us from our 1 to 2 o'clock position; so I told the first officer (first officer) to turn left away from it. It was getting very close doing erratic turns; dives and climbs. The first officer didn't respond which lead me to believe he didn't see the traffic; so I took the controls and began a sharp climbing left turn. I thought we had cleared it when the first officer said he saw it; it was coming back towards us again; at which point I then saw it going straight up; at our altitude; just in front of us. I immediately pulled the aircraft up into a much sharper climb; momentarily at about 30 degrees up. We flew past it within a few seconds. I returned the controls to the first officer; took a deep breath; and advised ATC what took place. The aircraft was not in radio contact with ATC.

Title: Captain reported flight crew was forced to take repeated evasive action due to another aircraft maneuvering near them without ATC contact.
Narrative: Climbing through about 8;000 ft. ATC advised us of VFR traffic at our 1 o'clock; around 3 miles away. It was maneuvering erratically. I immediately saw it. It was performing aerobatic maneuvers. It seemed to me to be rapidly coming towards us from our 1 to 2 o'clock position; so I told the FO (First Officer) to turn left away from it. It was getting very close doing erratic turns; dives and climbs. The FO didn't respond which lead me to believe he didn't see the traffic; so I took the controls and began a sharp climbing left turn. I thought we had cleared it when the FO said he saw it; it was coming back towards us again; at which point I then saw it going straight up; at our altitude; just in front of us. I immediately pulled the aircraft up into a much sharper climb; momentarily at about 30 degrees up. We flew past it within a few seconds. I returned the controls to the FO; took a deep breath; and advised ATC what took place. The aircraft was not in radio contact with ATC.
