Popular apps/websites that display your online status to strangers?

Anyone know a few off the top of their head? I'm trying to drop off the face of the earth. I don't care at this moment about what usage data the companies collect as long as randoms can't see if I'm online or not. (last online status also counts)

Off the top of my head: Reddit, Instagram, Facebook, Telegram, Discord, Steam, Ubisoft Connect, EA Origin, Microsoft Teams, Skype (but who uses that anymore)

Thanks!
