For a long time now, imgur simply hasn't worked for me unless I whitelist JS for medialab and a bunch of other 3rd-party domains. Even direct image links get hijacked back to the tracking-infested page. Good riddance, imgur, you won't be missed.
The redirect is geo dependent FYI. Never had it in Germany (tested without ublock a while ago, might have changed without), but I've read of US users having this happen years ago
