Ryan Kopf, the organizer behind QC Anime-zing!, Anime-Zap!, Anime-Spark!, and several other conventions, was banned from Anime Milwaukee during the 2018 convention due to a sexual assault allegation involving the Milwaukee Police Department. Kopf was at the convention as part of his other event, Anime Midwest and denies the allegations.

On December 14, 2015, Ryan Kopf sued Trae Dorn and Christopher Sturz of the Nerd & Tie website for defamation. The case was dismissed in October 2022 for "failure to prosecute" when Kopf failed to present evidence. On May 17, 2023, the defendants filed for sanctions against Kopf citing 15 witnesses willing to testify about sexual assault by Ryan Kopf. The filing cited incidents of rape, molestation, and sexual assault.

In November 2021, it was revealed that convention attendees for QC Anime-zing!, Anime-Zap!, Anime-Spark!, and any other conventions which had used the registration system developed by Ryan Kopf had also been signed up for his anime-themed dating website, MaiOtaku. People, including minors, had been added without consent and profiles were publicly visible on the dating site. Ryan Kopf claimed it was part of a "Single Sign On" system and denied that users' personal information was shared outside the scope of the site's privacy policy, and claimed that users were actually creating the profiles in their attempts to search for them on the system. MaiOtaku's privacy policy page made no direct reference to AnimeCon.org or the associated conventions.
