A [shill] is a person who publicly attempts to constitute, increase or sustain credibility and/or approval of/to an entity without disclosing that they have a relationship with [the entity], understating the type, importance or closeness of said relationship or concealing the actual role in which they perform for said entity.
The goal of the the shill is a (expected) personal benefit, may it be profit (participation), wage, payment by result or enabling, increasing or sustaining the chance of success for a specific socio-economic or socio-political project.
[The entity] can be either a person or an organized or [disorganized] group. Organized groups have some level of structure and decision-making ability while disorganized groups dont.
Organized groups can be the government, [politicial] parties, profit-oriented companies, investment or interest groups (hedgefonds, [freemasons]) or non-profit non-government organizations like non-profit companies, charities, churches or cults. [Disorganized] groups can be religions or unreligious cosmovisions (atheism, [humanism]), permanent political ideologies (f.e. communism, capitalism) or temporary political interest groups (f.e. pro-life-movement for abolishing the right to have an abortion).
The difference between [shilling] and expression of opinion is that the benefit is received from an external rather than an (emotional or intellectual) internal source or that the external force dominates the internal motivation.
