ShadowCheck: Reddit Filter & Visibility Checker for Marketers and Contributors
Reddit's automated spam filters silently remove posts and comments without notifying the author, making content completely invisible to others while appearing entirely normal to the creator when logged in, leading to wasted time and false assumptions about content quality.
Is the problem real?
Reddit's automated spam filters silently remove posts and comments without notifying the user, making content invisible to others while appearing completely normal to the author.
EVIDENCE
My posts and comments in another sub have been invisible for a month and nobody told me

Felt like I'd been shouting into a pillow for a month.
commentThat slow realization is the worst part, thinking you're just boring when actually you're a ghost. Had this happen with a whole account once, I'd been posting for weeks and getting nothing back, figured I just wasn't funny. Checked from a friend's phone and every single comment was gone. Felt like I'd been shouting into a pillow for a month. Reddit's spam filter gets weirdly aggressive with newer accounts in certain subs, especially if you've ever posted a link anywhere on the site. It doesn't reset cleanly either, you can have good karma elsewhere and still be shadowbanned in one specific community. The mods probably never even saw your message because modmail is a disaster zone. Your advice about the private window check should be pinned somewhere. I do it every few weeks now just to make sure I'm not talking to myself. The fact that Reddit shows you the comment like nothing's wrong is almost malicious, like they're actively trying to waste your time.
Who feels this pain?
TARGET USERS
Solo founders and digital marketers regularly posting content and discussions on Reddit who suffer from silent post and comment removals by automated filters.
Context
Current Workarounds
Where's the gap?
EXISTING SOLUTION GAPS
OPPORTUNITY & VALUE
Repeated complaints about content getting silently filtered across multiple accounts without any notification or feedback from the platform interface.
Purpose-built for instant automated visibility checking without requiring manual incognito window lookups.
A lightweight browser extension and dashboard that automatically monitors and verifies the public visibility of a user's published Reddit posts and comments in real time, alerting them immediately if content is caught in filters.
How does it make money?
MONETIZATION
Model
Founders spend hours crafting content for Reddit marketing; discovering days later that everything was silently filtered wastes substantial marketing time, making a $19/mo tool high-ROI.
How do you ship it?
MVP PLAN
“Know instantly when Reddit filters hide your posts.”
A lightweight browser extension and dashboard that automatically monitors and verifies the public visibility of a user's published Reddit posts and comments in real time, alerting them immediately if content is caught in filters.

RISKS & ASSUMPTIONS
Top Risks
Changes to Reddit's API policies or strict rate limits could break automated background checking functionality.
Automated verification routines might run into platform blocks if interpreted as aggressive scraping.
Casual redditors may not pay for visibility checks, limiting monetization strictly to active marketers and founders.
Should you build it?
Run an Investment Memo to get a structured Go / No-Go verdict, competitor landscape, unit economics, and a 90-day validation roadmap for this opportunity.
Generate an investment memoWhat this score means
This opportunity scores well above the median for ideas surfaced by MonetScope, with a validation sub-score of 9/10 against 3 independently sourced evidence signals. A "strong" rating in this band typically means the pain signal is consistent and recurring across multiple discussions, but one of the three pillars (severity, willingness to pay, or competitor weakness) is somewhat softer than top-tier opportunities. Founders evaluating this should focus customer discovery on the softest pillar first — confirming the gap before committing engineering time to a build.
Why this matters for SaaS founders
It sits at the intersection of "browser-extension", "devtools", "marketing", which makes it relevant to a specific subset of founders rather than a generic horizontal opportunity. SaaS opportunities at this stage tend to win on the strength of their initial wedge — a single workflow that the target user runs every week, where the existing solution is either spreadsheets, a clunky incumbent feature, or a manual process they hate. The build cost is moderate; the distribution cost is everything. The MonetScope pipeline surfaces this category alongside other saas signals, which is why it appears here rather than in a generic "trending ideas" feed.
Scores are derived from real forum discussions across Reddit, Hacker News and X, weighted by evidence volume and signal quality. How scoring works
Frequently asked questions
Is "ShadowCheck: Reddit Filter & Visibility Checker for Marketers and Contributors" a real validated startup idea or just an AI-generated suggestion?
MonetScope does not generate ideas from a language model's imagination. Every opportunity on this site is anchored to specific source posts and comments from real public discussions — typically on Reddit, Hacker News, or X — where actual users describe the pain in their own words. The AI's role is structuring, scoring, and grouping those signals into a navigable opportunity, not inventing the problem.
How recent is the underlying data for browser-extension?
MonetScope's spider pipeline runs continuously and surfaces opportunities as new evidence accumulates. The "Updated" date in the header reflects the most recent re-scoring of this specific opportunity. Most saas opportunities visible in the public catalog draw from discussions in the last 30-60 days; older signals are de-prioritized because user pain shifts faster than most founders assume.
What's the difference between "overall score" and "validation score"?
Overall score is a composite across six dimensions — pain, urgency, willingness to pay, market size, defensibility, and execution ease — designed to give a single number for triage. Validation score is narrower: it asks "how cleanly does the same signal repeat across independent sources?" An opportunity can score high on overall but lower on validation when one or two large discussions dominate the evidence; conversely, validation can be high on a smaller-overall idea where the signal is consistent but the addressable market is modest.
