Danny Whisken, of Chaucer Way in Dartford, caused criminal damage without lawful excuse between January 31 and March 9, 2024.
The 33-year-old was repeatedly using spray paint to alter postboxes in distinctive colours and patterns which falls under sections 1(1) and 4 of the Criminal Damage Act 1971.
The majority of the postboxes were repainted in the Temple Hill area.
It is currently unknown how much the damage has cost, but the postboxes are owned by Royal Mail.
Whisken was first arrested on February 13, but was released on bail pending further inquiries by Kent Police.
After continuing the graffiti spree, he was re-arrested on March 9 and remained in custody.
Whisken pleaded guilty on March 11, 2024 at Medway Magistrates Court.
He is currently released on conditional bail until his next hearing on May 31 at 10am.
His bail conditions include a ban on possessing spray paint or paint products in public spaces.
A variety of patterns have been seen on the postboxes – on February 4, a postbox on Farnol Road was seen sporting a black and white pattern that looks a little like cow print.
