A black bloc is a tactic used by protesters who wear black clothing, ski masks, scarves, sunglasses, motorcycle helmets with padding, or other face-concealing and face-protecting items. The clothing is used to conceal wearers' identities and hinder criminal prosecution by making it difficult to distinguish between participants. It is also used to protect their faces and eyes from pepper spray, which is used by police during protests or civil unrest. The tactic allows the group to appear as one large unified mass. Black bloc participants are often associated with anarchism, anarcho-communism, communism, libertarian socialism, antifascism, or the anti-globalization movement.

Bullshit Detector was the name of a series of compilation LPs put together by the anarcho-punk band Crass and released on their Crass Records label. Three editions were released between 1980 and 1984, consisting of demo tapes, rough recordings and artwork that had been sent to the band. The sound quality of the Bullshit Detector series was mixed, and was often very basic or poor as Crass would master the tapes directly to record without any additional production or enhancement. For Crass, the expectation of a polished performance was missing the point of the DIY punk ethic:"Don't expect music when the melody is anger, when the message sings defiance, three chords are frustration when the words are from the heart"

Crass Records was an independent record label which was set up by the anarchist punk band Crass.

Food Not Bombs is a loose-knit group of independent collectives, sharing free vegan and vegetarian food with others. Food Not Bombs' ideology is that myriad corporate and government priorities are skewed to allow hunger to persist in the midst of abundance. To demonstrate this and to reduce costs, a large amount of the food served by the group is surplus food from grocery stores, bakeries and markets that would otherwise go to waste, or occasionally has already been thrown away. This group exhibits a form of franchise activism.
