If you landed on memo1-dp8vlxvc9pag.edgeone.app expecting a working website, you found a blank 404 error instead. A legitimate business or even a personal project would typically serve actual content and provide some way to reach someone. Here, the page just says 'NOT_FOUND' and offers no clues about who runs it or what it was supposed to do.
There's no way to run a standard trust check because the site doesn't exist in any practical sense. It has no privacy policy, no terms of service, no social media presence, and no history in the Wayback Machine. The domain itself is hosted on a generic CDN subdomain, which is not unusual for test pages or temporary setups — but that's exactly the problem. You can't tell if this was a scrapped project, a parked domain, or something set up for a short-lived campaign.
The bottom line is this: if a site won't load, there's nothing to evaluate. Move on and look for alternatives that actually provide the product, service, or information you're searching for. No one can say whether memo1-dp8vlxvc9pag.edgeone.app is a scam or not — the evidence simply isn't there — but a dead site can't serve you, and there's no reason to trust it with your time or data.
