A group of users began alerting Reddit to a rash of suspicious news postings a year before Facebook and other tech platforms identified them this week as an Iranian disinformation campaign, NBC News' Ben Collins reports. The users tied the postings to Iran using publicly available domain registration information.
Why it matters: Tech platforms often ask for users' help to flag inappropriate, spammy, or suspicious content. In this case, the users complain that they couldn't get Reddit administrators to respond or act.
