A good place to start is the QRD paste from 2019.

There was also his activity on /vg/ (/gig/, /hsrg/, /anii/) in the 2020s, I think he might have been on /wowg/ in 2018 also.
He was also on /vp/ at certain points in 2017 and more famously in 2024 in Pokemon Go threads where he became known as the Solar Beam Schizo or Solarfag after an argument, until someone recognized him as ACK and he instantly started melting down about !Akemi.
Then there was the time in early 2026 that he used owo[.]vg and became a mod on awoo[.]cf after begging Leto for mod status after baiters found the meta thread and started posting bait. He later got banned due to a abusing his mod status and Leto banned him from owo for getting IPs banned for spamming 4chan.
A lot of ghost threads with hippo OPs were hotbeds of ACK posts and baiting during 2025 after the 4chan hack. His Twitter account Candysfx got leaked there and he started spamming threads to "hide" posts he hated after the admins stopped deleting threads he mass reported.
