OpenAI and Reddit reach deal that will give ChatGPT access to content on the social media platform.
Anyone can download a torrent containing historical Reddit comments, Reddit surely has at least that if not a full edit/delete history of all the comments. The only people you are thwarting by deleting your comments are other humans who may stumble across your old threads in Google.
I can't agree with this enough. People are extremely fucking naive if they think the comments are actually gone.
And also they're posting about it on a completely open platform that any AI trainer could trivially be "harvesting" as well.
