Reddit is removing the 1000 submission/comments limit on user profiles. Profiles will soon show all submissions/comments from day the account was created.
Reddit is providing a method to delete all content by emailing redditdatarequests@reddit.com or via their form https://support.reddithelp.com/hc/en-us/requests/new?ticket_form_id=360001370251
The submission link here on Lemmy takes you directly to a Reddit’s admin submission that talks about the change.
They just hide your submissions/comments beyond your 1000 most recent contributions from your profile. The contributions remain on the website. I’ve found the only method to find contributions beyond the 1000 limit was to Google it or use third party archive databases.
With the new change workarounds to find old contributions will not be needed.
