Proxies started getting blocked (by some auth-account methods) last year, but libreddit/redlib dev was able to outsmart them multiple times. Now it seems like reddit is blocking IPs (and/or IP ranges). Running redlib from a residential IP still works, but I would not expect it to work from a VPS.

I don’t watch a lot of youtube, but DuckDuckGo browser (on Android and Windows, at least) has a Duck Player that removes all of the cruft around videos and is private afaik.
