Real Blacklists are lists of complaints of bad experiences by actual users.
Blacklists help consumers understand what can go wrong and what happens when criminals or incompetents help things to go wrong to increase their profits or completely steal money from “customers”.
Normally blacklists are not published - they are traded between groups with similar interests.
Schools will trade information about bad teachers and bad agents to avoid hiring mistakes and losses.

Students and parents will trade information about bad schools, bad teachers and bad agents.
Teachers have blacklists of agents and schools that do not pay or provide visas or services.
