And the Tor onion link: https://old.reddittorjg6rue252oqsxryoxengawnmo46qy4kyii5wtqn...
The problem is that Reddit has started sometimes generating these links with /s/ in them, which are supported by new Reddit (www.reddit) but not by old Reddit (old.reddit). Given Reddit’s track record, I am certain this is the latest in a series of intentional moves to gradually tighten the thumbscrews to make old Reddit less useful, so enough users will switch to new Reddit to justify closing old Reddit down.
