Transcript: See something off? Do your part to keep the Lemmy community safe:
R - Read the rules of the community.
E - Explain your report, including rule # when possible.
P - Provide context the mods should know.
O - Opt-out, disengage, downvote or block. Don't add to the drama.
R - Reach out or report right away. *For extremely time-sensitive content (CSAM, gore) DM an admin via Matrix: Instance homepage > Sidebar > click admin's @username > Send Secure Message
T - Trust your instincts. If in doubt, report it.
Can i report without evidence?
No. Unlike reddit, when you send a report, it shows who reported it.
This has the advantage of the mod being able to respond to the reporter to ask clarification or provide explanation, but it also allows malicious mod action.
I suppose you could create another account if you need to report something without using this name.
That seems like a pretty big oversight on the Lemmy development side of things. There should, at the very least, be an option to submit a report either anonymously or to have it tied to your account. A disclaimer could be included that anonymous reports cannot be responded to in case that is a concern for users.
It’s probably not so much an oversight as a natural consequence of the open nature of Lemmy. Same reason DMs on here are not technically private. Even if you implemented an anonymous report feature, instance admins could probably identify the user easily.
