Regular sleeper agents just infiltrate a country or organization and then don ' t do anything for years . But you probably mean one with altered memories . Hypnotism or other forms of mind control can wear off quickly , so they would require constant reprogramming , which would defeat the whole purpose . So basically they don ' t exist . <| sep |> Arbitrary detention occurs when people are detained without reasonable suspicion to justify an investigation . Arrest is irrelevant . The reality of carding is that police use tactics such as physical intimidation , lies and threats which invoke psychological detention in entirely noncriminal circumstances . <| sep |> I remember this ! People I know including my best mate were interviewed by Vice . Of course , they edit what people say a lot . As me and my friend agree , the account was right to do so People will say gross stuff just for the meme , and bring down the family value and appeal of a brand . It did go a little far , blocking people with animal profiles or something is stupid , but furries got kinda bad about it . It wasn ' t to do with hating furs , it was to do with not putting weird shit on a major social media representative .
