my mobile phone encountering this currently. after 1min of browsing it pops up and block the page. people have use ublock to try to remove it manually, but it also reported that reddit is aware of that, one thing i notice, it hides the comments until you login. its seems they are testing the waters, likely trying to identify all the attempts to block it, and then bypass altogether.

on desktop you still can block it, but who knows when reddit will get rid of that option too. they are mimicking METAS aggressive account login.
