The Federal Trade Commission and Department of Justice, together, brought back preservation guidance on collaboration app data in a new statement—this time, with a novel warning: “Feigning ignorance” on the matter won’t be tolerated.

Both agencies are in the process of updating the language “in their standard preservation letters and specifications for all second requests, voluntary access letters, and compulsory legal process, including grand jury subpoenas, to address the increased use of collaboration tools and ephemeral messaging platforms in the modern workplace,” according to the notice.
