On May 4, 2011, Circus-P deleted many of his Youtube videos. Later, he closed his accounts on sites such as YouTube and DeviantArt. It was confirmed that these sudden actions were made because he had admitted to using POCALOID and wanted a hiatus for maturity. Circus-P eventually reactivated his DeviantArt account, made a new YouTube account with a humorous username, and is currently uploading videos using legal software.

Because of his POCALOID incident, many users still believe he is using them still even today. However, that was proven wrong, since he had posted a picture of all of his owned VOCALOIDs on Twitter.
