Launch week: every idea card is free.Get Pro

SaaS ideas, mined from what people actually complain about.

Every idea comes from real Reddit posts, was researched against today's competitors, and survived an independent skeptic before it made the list.

Free-Tier Abuse and Fraud

Users exploit free trials and signups with fake or multiple accounts to burn credits, resources, and commit fraud.

In their words

I could have noticed this anytime in the last few years simply by spending 5 minutes looking over Am Ex statements.

r/Entrepreneurs on Reddit

I'm critically short on time and need to outsource it.

r/ecommerce on Reddit

CF automatically accepting these abuse complaints and then only intervening once I contact them 8-12 hours later.

r/CloudFlare on Reddit

the service actually flagged it sometimes at 100% likely as fraud, but if they submit a valid ID it overrides that

r/highereducation on Reddit

the reinstated dormant authority check is the real one, thats the pattern on almost every double brokering ring right now

r/FreightBrokers on Reddit

people show up with throwaway emails, grab the free stuff, and bounce

r/smallbusiness on Reddit

the APK had appeared on several pirate APK websites

r/gamedev on Reddit

I got ip-banned and they told me it was because I had a typo in a URL I entered.

r/sysadmin on Reddit

It has turned into a constant game of whack-a-mole.

r/SaaS on Reddit

I get stuff like this all the time and I'm not sure how Rover dips their hands into 31% of funds and still lets people make accounts like this

r/RoverPetSitting on Reddit

getting destroyed by free tier abuse and I don't know what to do

r/SaaS on Reddit

the same guys who try to do a “freebie” show… go in and out of my private show PURPOSELY under 30 seconds to not get charged

r/CamGirlProblems on Reddit

if I have another signal, I want to know whether they are redundant or complementary, to avoid interpreting two positives as independently verified.

Hacker News

If I can filter/throttle fraudsters at the create account step for free, I save on the fees
