Tumblr - my first real main social media platform, mainly fandom stuff, used to post fanart there as well, I’ve been on that hellsite for half of my life now and will probably stay there until Automattic pulls the plug
Mastodon - My main Twitter replacement, really good for fandom since it’s easy to talk about spoilers with custom CWs
Bluesky - Second Twitter replacement
Lemmy - As reddit replacement with less lazy engagement bait posts (this is really a problem on reddit especially in game-(dev) subreddits
Discord - for Gaming-buddies, fandom communities, and gamedev communities
