Use PreserveTube to save videos, except don't archive pointless slop or he will be mad at you o algo (he might even shut the website down like he did with Spy.pet/dis.cool)
Pro-tip: save and compress it locally to your own device, DO NOT TRUST ANYONE ELSE SINCE YOU CAN'T RELY ON THEM, EVERYTHING YOU LOVE WILL EVENTUALLY DISAPPEAR FOREVER AND EVER IN THE NEAR FUTURE, EVEN INTERNET ARCHIVE WILL DELETE SAVED SNAPSHOTS AND FILES, RECORD EVERYTHING YOU SEE, SAVE IT ALL,
SAVE IT ALL
