Post spreading on twitter, summary of the show. Feels good man.
I think in this context they just meant to use "markers" linguistically:
-Marker-
: something that serves to identify, predict, or characterize
: something (such as a sign or an object) that shows the location of something
: something that shows the presence or existence of something
The black hats had their own plans and goalposts (markers) that they've been following, & know it's all crumbling before them.
