Hm, er ei bod yn ymddangos eu bod eisiau gwneud pethau'n well na Facebook a Twitter, mae uBlock Origin yn dangos llawer o hysbysebion / tracwyr: https://www.directory.trade-free.org/wp-content/uploads/2020/11/Pasted-12.jpg - ac mae'n berchnogol! yn seiliedig ar hynny dim ond 2 floc y byddaf yn ei roi iddynt.

Friendica or other social networks from the Fediverse (https://fediverse.party/) seem to be way better, since they are open-source and decentralized.

I joined that network a while ago. They say they will never sell your data and “our platform survives on the generosity of individual donors to ensure privacy is protected and your social space is ad-free.” Based on that it seems to be likey trade-free. However I spotted a trade on the register site where they say you need to be 13 years or older to register. Also they do collect some data about you when you register: https://wt.social/data-transparency – but I’d see these more like essential to run a social network.
