Manuel Castro Jr., a West Hollywood artist, entered a plea of no contest plea on Friday.
You may remember his work - Castro painted a picture of a cow and the words: "Tastes Like Hate." He was protesting the Chick-Fil-A president's comments against same-sex marriage.
He was arrested after allegedly claiming responsibility for the graffiti online.
In addition to the probation sentence, Castro will have to serve 200 hours of community service and pay $800 in fines.
He was ordered to stay away from Chick-Fil-A restaurants for the term of his probation. He was also barred from possessing any paint, paintbrushes, spray paint, aerosol cans or vandalism tools outside his home. A restitution hearing was set for Jan.9.
