Bluesky example needs a way to double check content in teleportation tag against meta tags

[zach-planet-nine]

Since teleportation tags can have arbitrary content, a client that implements them trivially can dodge a platforms content filter. I think the near-term quick solution to this is to simply ensure that the content in the teleport tag matches whatevers in the og and twitter tags for bluesky, but I want to think about it more, and not do it right now lol. Open to other thoughts.
