Anonymization
-------------

Generally, all data presented in this paper (mostly microtask descriptions) is anonymized. Most of the actual URLs, person and company names, and other named entities are replaced with the string $<REDACTED(...)>$. When there are several URLs or names within one example though, they are replaced with their own unique label so that they are not mixed up. Other than this modification, the job descriptions are copied herein verbatim.

Obviously, some basic URLs like Facebook.com or fakenamegenerator.com, for example, are kept because they are reported only for uncovering the campaign method but not its content, and also because the job descriptions would not be as understandable
