24 hour ops 

When a group of individuals on a forum (i.e. Discord, Kiwi farms, 4chan, or any imageboard service) begin to dig up any information on a subject, whether it be a persons name, location, or anything dealing with finding something usiing the internet. Anything they find will be widely archived, documented, and shared with everyone involved, which will most likely be used as a smear campaign, a news break on any e-celeb, or anything that could possibly be used to humiliate a person, or cause any reaction for entertainment.

The He Will Not Divide Us flag takedown of early 2017 is an example of 24 hour ops.
