All media uploaded to Senden is automatically checked for abusive content, including child sexual abuse material (CSAM) and other illegal imagery. These checks happen entirely on our own infrastructure in Switzerland. Nothing is ever sent to a third party scanning service, cloud API, or external provider.
Keeping detection in house matters: it means your media is never handed off to companies that might retain, analyze, or share it for their own purposes. Abuse detection and user privacy aren't in conflict here.
Harassment, threats, and targeted abuse are not tolerated on Senden. If someone is making you feel unsafe, you have options: you can block them, leave the conversation, and most importantly report them to the moderation team.
Every message, profile and Server on Senden has a Report button. Use it any time you see content that violates our terms. Reports go directly to the moderation team.
When you report a message, include as much context as you can. That helps us resolve the issue faster and make a better decision.
Senden can't read end to end encrypted messages on the server. That's the whole point of E2EE. So reporting one works a little differently: when you hit Report on an encrypted message, your client decrypts the reported message along with the 10 messages before and 10 after for context, and sends that bundle to the moderatio team. Without context, a single message out of a long conversation is almost impossible to judge fairly.
There's a catch: because the reporting user is the one decrypting and submitting the messages, we can't verify that the content actually came from the person being reported. Someone could, in theory, forge a report. To handle this fairly, moderators don't just look at the reported content. They compare the reported user's overall behavior against normal user patterns. Repeated reports, behavioral anomalies, and usage can all factor in.
This approach isn't unique to Senden. Signal uses the same principle for handling reports in its encrypted conversations. It's the fairest way we know to balance end to end encryption with moderation against harassment and illegal content.
When a report is finalized and action is taken, multiple moderators must sign off on the decision . No single moderator can ban a user, remove content, or close a report on their own. This prevents biased resolutions, personal grudges, and mistakes from turning into action against a user.
It adds a small amount of overhead to the process, but it guarantees that every enforcement decision has been reviewed independently by more than one person.
Unlike other platforms where reports disappear into a black hole (not pointing fingers) and never get a response, Senden aims to resolve issues as quickly as possible . Reports are looked at as soon as a moderator is available.
The current average time from report to resolution ranges between 1 and 14 hours, depending mostly on which timezone the moderator is in when the report comes in. As the team grows and coverage expands across more timezones, we expect this window to shrink further or stay the same because of the amount of reports.
Urgent issues, such as threats of violence, active harassment, illegal content are prioritized and handled first, regardless of queue order. We trust you not to abuse this. If repeated abuse is observed, we might depriorize your future reports.
