It takes 20 years to build a reputation and five minutes to ruin it. If you think about that, you’ll do things differently. – Warren Buffett

This quote by Warren Buffet :

Warren Buffett

is something any entrepreneur that have been long in business knows. This should be a warning to young money hungry entrepreneurs, to focus on integrity, because once you get a bad reputation, your business is not going to get over it. And honestly in my opinion it would be better to re-brand.
PS: Reviews are very important, keep an eye on your reviews and prevent competitors from sabotaging your business!
