Which act is referenced regarding improper conduct like scare tactics or block busting?

The Federal Fair Housing Act is the correct reference when discussing improper conduct in real estate practices, such as scare tactics or blockbusting. This act, enacted in 1968 and modified in subsequent years, prohibits discrimination in housing based on race, color, religion, sex, national origin, familial status, and disability.

Scare tactics and blockbusting are methodologies employed by some real estate agents or entities to induce panic selling or to manipulate property values, often targeting specific demographic groups. This practice is explicitly addressed and condemned under the Federal Fair Housing Act, which aims to promote equal housing opportunities and eliminate discriminatory practices in the housing market.

While the other options mentioned, like the National Housing Act and the Equal Housing Opportunity Act, deal with various aspects of housing and lending, they do not directly target the predatory strategies like scare tactics and blockbusting in the same way the Federal Fair Housing Act does. The Consumer Protection Act focuses more broadly on consumer rights in various markets rather than specifically housing discrimination practices.
