How to send a notice of claimed infringement under the DMCA to Catalyst’s designated agent.

Last updated October 15, 2026

Designated agent

Catalyst does not screen uploads. The terms say what creators may publish, and notices of claimed infringement under the DMCA handle content that ignores them. They go to the designated agent, by email or with the form below.

Send a notice

Each part of the form is an element the statute requires, so a notice that skips one cannot be actioned. A complete notice is actioned promptly: the material comes down, the creator is told and may answer with a counter-notice, and we tell you at each step. A knowingly false notice can make you liable for the damage it causes.
