1 Answer 1


This has actually become the BDLPSWDKSS effect because it suffers additionally from the

Streisand effect, i.e., hiding some information has increased the chance of it becoming publicly known.

We can find this in the picture by

counting which word is redacted on each row and taking the corresponding letter from the name in the BDLPSWDKS effect as indicated in the censor bar. I.e., since the first word is censored on the first row and the censor bar indicates Sapir, the fifth name, we take the first letter of Sapir. Doing this gives,

Whorf (this name is redacted but can be found in the original)

spelling out STREISAND.
