disreputable
dishonorable / shady / low-quality / untrustworthy
Adjective
This term carries a strong social stigma, suggesting a lack of integrity or a history of questionable behavior. It is often used to describe people or establishments that are viewed with suspicion or disdain by the general public, implying a moral failing rather than just a lack of fame. When applied to physical locations or services, it shifts from a moral judgment to a critique of quality and legitimacy. In these cases, it describes environments that look shabby, untrustworthy, or operate on the fringes of legality, evoking a sense of seediness or unprofessionalism.
