I only use new to “refresh” my list of filtered content:

• AI generated images
• The bazillion of RSS bots that host no discussions and just post 5 threads in a row
• Non-English content that I can’t read anyway (not their problem obviously)
• Porn
• Thirsty anime models
• I probably forgot some more content I’m not interested in

Do you use “new” for anything specific?

edit: I listed “spam” in the title originally, I felt this was unfair
