As online spaces start to demand I dox myself, I will remove myself from those online spaces (see: Reddit). If that means I ultimately leave the internet as a whole, then so be it.

Lemmy didn’t try to force me to dox myself for “age verification”.

One other thing to try: https://addons.mozilla.org/firefox/addon/video-downloadhelper (presumably also available for other browsers). Then hold shift while you reload the page, and play the media. Chances are extremely good the addon will catch it and start dancing in your toolbar. Open the addon, click the file you want to download, and it should just download.
