I was wondering what the tag Ricardians for ts means?

I’ve seen it a few times, however I haven’t been able to figure out what it means. You wouldn’t mind please telling me what it means, would you?

Hello! 'for ts' is an old tumblr expression for tagging content that might be annoying or triggering — 'for ts' literally means 'for tumblr savior', a tool to hide posts which contain certain words or phrases once you have them saved in your settings (like you can do on XKit). I tag ricardian discourse as 'ricardians for ts' so people who are not interested in the discussion or are annoyed by it can have their eyes spared. It's simply an old tagging convention on tumblr for aiding people who want to avoid certain content.
