These aren’t websites — standard DMCA doesn’t apply the same way.
Telegram and Discord aren’t web hosts. They don’t have a standard DMCA agent on file, they don’t accept notices in the same format as a website, and they don’t respond to the same escalation paths. Telegram processes abuse reports through its own internal system. Discord routes IP complaints through its Trust & Safety team. Both platforms require specific evidence formats, specific filing channels, and specific follow-up procedures that are completely different from filing a DMCA notice with a web host or search engine. Most takedown services don’t bother because the process isn’t automatable.
