was reading the wiki entry on totem poles and found this:
Shame poles
Poles used for public ridicule are usually called "shame poles", and were erected to shame individuals or groups for unpaid debts. Shame poles are today rarely discussed, and their meanings have in many places been forgotten. However, they formed an important subset of poles carved throughout the 19th century.
One famous shame pole is the Lincoln Pole in Saxman, Alaska; it was apparently created to shame the U.S. government into repaying the Tlingit people for the value of slaves which were freed after the Emancipation Proclamation. Other explanations for it have arisen as the original reason was forgotten or suppressed, however this meaning is still clearly recounted by a number of Tlingit elders today.

Another example of the shame pole is the Three Frogs Pole in Wrangell, Alaska. This pole was erected by Chief Shakes to shame the Kiks.ádi clan into repaying a debt incurred by three of their slaves who impregnated some young women in Shakes's clan. When the Kiks.ádi leaders refused to pay support for the illegitimate children Shakes had the pole commissioned to represent the three slaves as frogs, the frog being the primary crest of the Kiks.ádi clan. This debt was never repaid, and thus the pole still stands next to the Chief Shakes Tribal House in Wrangell. This particular pole's unique crossbar shape has become popularly associated with the town of Wrangell. It was thus used, without recognizing the meaning of the pole, as part of the title design of the Wrangell Sentinel newspaper, where it is still seen today.
A shame pole was erected in Cordova, Alaska on March 24, 2007. It includes the inverted and distorted face of Exxon ex-CEO Lee Raymond, representing the unpaid debt that courts determined Exxon owes for having caused the oil spill in Valdez, Alaska.
