Steal the Flags

Warning: Stealing flags is a serious business. Do not attempt to steal flags without proper training.

Flag of the Unseen

Located in a hidden dimension, this flag requires a PhD in Interdimensional Flagging to retrieve.

This flag has been lost for so long, even the flag itself has forgotten where it came from.

Due to a freak accident involving a possessed toaster, this flag can only be stolen by a team of highly trained, highly caffeinated ninjas.

This flag can only be stolen with a smartphone, a decent selfie game, and a good filter.

This flag is so hidden, even the flaggers themselves are unsure if it exists.

Remember: Stealing flags is not a joke. Or is it? Maybe it's a bit of both?
