Ok, just went there. My home is full of smaller subs reposting old high-quality stuff. I could even mistake that for good activity if I haven't seen it already.
Popular is full of useless shit... so no visible impact.
I guess one has to subscribe to the correct subs to see the implosion.
Im still using my custom app patched with my own API key. But it's slowly not becoming worth it with most of the smaller subs I follow only having 1 or 2 posts in the last week. Opposed to the 2 or 3 posts per day.
They also haven't actually kicked off third party clients for mods. If you moderate any sub (even just create a private sub now) and the client didn't purposely kill their own API key (Apollo and RIF did I believe) it will still work even without the patch.
It's getting pretty bad though. With most people who were truly pro-protest gone, average sentiment is "oh well protest failed let's get back to normal". I was pretty heavily downvoted in the Ask Historians meta thread about next steps for suggesting the mods/experts were fairly irreplaceable and they should look to move content off of reddit to their own site.
You can actually decompile any android app into smali code which is kind of a readable bytecode. Create an OAuth app on reddit and replace the developer's API key with your own. Free reddit app with no ads.
