When checking if biggestfish.substack.com is a scam, you first have to recognize it for what it is: a personal newsletter hosted on Substack. Unlike e-commerce storefronts that require deep verification of business history, professional blogs mostly rely on the reputation of the author. This site clearly labels itself as a collection of observations on software engineering, which matches the content found there.
Most high-quality technical blogs are updated periodically and focus on niche, professional subject matter rather than aggressive marketing. This site aligns with that profile perfectly. You should not worry about the lack of long-term archive history or the use of neutral branding, as these are normal for new independent writers.
If you find yourself reading biggerfish.substack.com reviews or wondering is biggestfish.substack.com fake, remember that the main risk with newsletter platforms is email spam or unwanted subscription solicitations. As long as you interact with the primary content and keep your personal credentials private, there is no reason to think this is a malicious actor.
