What's the deal with 407 -.3? Anyone else noticing this trend?

Wait, so 407 -.3 is actually a thing? I thought I was just imagining it!

Thanks for all the tips, y’all. I checked out the Discord server and the 407dash3 site, but it’s still a mystery.

Has anyone tried reaching out to the creators or accounts posting about it? Maybe they’ll spill the tea if we ask nicely. 😅
