I don’t know if you need this info, but I was pretty disturbed to see unexpected child pornography on a casual community. Thankfully it didn’t take place on SLRPNK.net directly, but if anyone has any advice besides leaving the community in question, let me know. And I wanted to sound an alarm to make sure we have measures in place to guard against this.
It should be reports and limited to users with some form of track record on the platform. So posted some time earlier, has gotten X likes, account age and similar measures to make sure it is not problematic.
Downvotes are a bad measure. They are often just done by somebody disagreeing with a post, which often are not exactly a problem. Also 10 is really low, when something really takes off. On the c/meme half the posts have more then 10downvotes, but nothing is really all that bad.
The best suggestion I have seen is to have a specific report category for CSAM. If a post is reported for CSAM x number of times, the post is hidden for moderator review. If it is a false report, the mod bans the reporting accounts.
Another issue is that post links can be edited. Trolls will definitely use this feature for abuse.
Ranking algorithms need to be adjusted so that if a post is removed like this, and then restored, it gets the same number of views it otherwise would have. Without that, a user-interaction driven automatic removal will get abused at scale.
You can see below in this thread herein that someone got >10 downvotes for a perfectly reasonable and civil post by people who merely disagreed with their comment. Automatic censorship would be overly interventionalist. I would not want to participate in a forum that auto-censored like that. Downvotes did their job – pushed the msg low on the page for reduced visibility.
