If I find that one of the content creators I follow on YouTube happen to post their content on any other platform, I switch my subscription to that platform.
Besides YouTube they support Nebula, Twitch, Odysee, PeerTube, Dailymotion, Bitchute, Kick, BiliBili, Rumble, Patreon, and more.
It’s also worth pointing out that your upvotes are public here (using something like kbin/mbin to view a lemmy instance). Downvotes could also be seen if some other instance connects to your instance and decides to display downvote information.
