The easement existed before Mr. Wayson took the land.  He was also aware of the easement on the land he purchased.  His actions, which he calls "mimicry" or "defamation" are legally prohibited under property law.  The owner of the burdened land cannot interfere with the easement by posting false signs or appearing nude next to it.
Also, the article states it is a commercial easement not a public easement.
