infamously

An infamy is when someone or something has a bad reputation, often because they've done something wrong. This word can also describe something that's very famous for being bad.

When people talk about infamy, they usually mean it in a negative way. Imagine you're watching the news and there's a story about a company that did something really shady to hurt its customers. If someone says "This company has become infamous for scamming its clients," they mean that it's very well-known for doing something bad, but not in a good way. It's like being famous, but instead of being loved or admired, you're known for being annoying or troublesome.
