Gather the links
- Copy the t.me link to each offending message or channel (Message → Copy Link).
- Note the channel @username.
File the report
Email dmca@telegram.org for copyright removals, or use Telegram's abuse/ NCII reporting for non-consensual intimate imagery. Include the t.me links, a statement of ownership, and your signature. Telegram acts on public channels; private ones are harder and may need the NCII route.
Proactive blocking
For intimate imagery, submitting a perceptual hash to StopNCII means participating platforms block re-uploads automatically — prevention rather than chasing each new channel.
