View source worked for me, but there's a couple of tricks to it I think...maybe.
First I made sure I was on the channel's main page and not one of the channel's videos. Then I did right-click "view source". The source is all smashed together (unformatted) of course. It's annoying to search and read like that, so I copy-pasted the source into my favorite text editor and was able to find "channelid" it that way.
500 seems like a lot, but I could see mine creeping up to that, given enough time. There are a lot of pedantic types online, they're a trope at this point.
Mine have a tiny little chip in the coating on the right lens, it's so annoying. If I take it in for repairs it will cost an arm and a leg so I just live with it. I have a 2nd pair but I'm keeping them pristine for as long as I can before I give up on these.
I'm glad you mentioned airplane mode. I noticed something interesting about my Kindle after I set up a Pi Hole on my home network. The kindle would constantly try to connect to the Amazon mothership. Because the Pi Hole was blocking it, it would try it over and over again and this quickly depleted the batteries (maybe trying to boost it's WiFi signal? I'm not sure). Putting it into Airplane mode helps preserve battery life noticeably, back to what it was before I installed the Pi Hole.
More hilarity: as of about a week ago, it appears the reddit algorithm has also started boosting posts with negative karma on their horrible mobile app. Guessing it's a move towards 'negative engagement'. I have not seen it myself (I don't use the reddit app) but I see users complaining about it.
You could try court records in various states, but Florida has some of the most complete and easily accessible court records online. Try Miami-Dade or Orange county records and start searching.
At reddit, line must go up. So user experience must go down.
