Photon has a feature on links which gets data from Media Bias Fact Check to determine its media bias. However, I've seen controversy on lemmy.world's bot with this, and I'm not sure if this is the best place to get the data from.
Should I use a different dataset? like allsides'?
The whole website bias rating is flawed by design. Each publication have multiple authors, which have different inherent biases and personal leanings that even unconsciously can influence the writing. And while corporate influence does exist and politics are unavoidable, labelling everything a site published based on a small dataset just makes the situation worse.
I was afraid that Photon will go the same route as Tesseract (originally fork of Photon) who went all into in flawed media bias checking and ruin the good project, but having the button for people that care about it is a good compromise.
As far as MBFC specifically, https://slrpnk.net/comment/10200142 highlights the issues with it quite well.
https://spinscore.io is a relatively new tool, but shows some promising results so far.
