The project 'Samurai by FeeFighters' was a legitimate and innovative payment gateway circa 2010-2012, culminating in an acquisition by Groupon. However, this submission appears to be for a 'zombie' or legacy version of the project (or a domain revival) with no verifiable current activity. The submission contains hyperbolic and demonstrably false claims regarding traction (e.g., 'most people have used my product'). While the original technology had high utility, the current iteration shows no evidence of market fit, active user base, or revenue. The response quality is extremely low, lacking specific metrics or modern context.
