Free Trial Abuse
A freeloader signs up, burns through your trial, and signs up again with a different email. Over and over and over. Free trial abuse is the most common form of SaaS abuse, and traditional defenses — email verification, IP blocking, CAPTCHAs — do little to stop the freeloading. Dregs has a few tricks up its sleeve, though.
The Freeloader Problem
Free trials are essential for SaaS growth. They let legitimate users experience your product before committing. But they also attract people who have no intention of ever paying, and these freeloaders are surprisingly resourceful.
A typical free trial abuser creates a new account every time their trial runs out. They use a fresh email address (disposable providers make this trivial), sometimes a VPN, and occasionally a different name. To your application, each signup looks like a brand-new user.
Sadly, the conventional SaaS defenses don't work all that well against free trial abusers.
These free trial abusers present to your system as legitimate users. It's easy to see the abuse problem in aggregate, but hard to systematically prevent individual freeloaders.
What Free Trial Abuse Costs Your Business
Free trial abuse isn't just annoying — it actively harms your business by messing up your analytics and degrading your ability to serve your real customers.
Polluted metrics
Your signup stats, activation rates, and conversion funnels are polluted with users who were never going to convert. Product decisions based on these metrics are likely to be wrong.Wasted resources
Every freeloader consumes compute, storage, bandwidth, and other infrastructure that you're paying for. Free trial abuse eats into your profit margins and shortens your runway.Support burden
Identifying and blocking free trial abusers takes support cycles away from your customers. Some freeloaders even contact support and are likely to badmouth you if they don't get their way.How Dregs Detects Free Trial Abusers
Dregs has a pipeline of AI-assisted analyzers that detect free trial abuse from many angles at once. A determined freeloader might beat one or two signals, but beating all of them is unlikely.
Uniqueness Score
When the freeloader signs up again, Dregs recognizes the device fingerprint, even if everything else is different. The new account shares a device with the previous one, and the Uniqueness score of both accounts drop immediately. No cookies required, just hardware characteristics that persist across accounts and incognito sessions.
Authenticity Score
Repeat abusers tend to get lazy with fake identities. The Authenticity score catches disposable email domains, names that don't follow natural patterns, and data that doesn't hold together. Especially when combined with a low Uniqueness score, low Authenticity is a strong indicator of free trial abuse.
Behavior Score
Freeloaders know exactly where to go and what to do because they've done it before. The Behavior score picks up on unnaturally efficient navigation, repetitive patterns within or across accounts, and other user activity that doesn't match a genuine first-time experience.
Identity Relationships
Dregs looks beyond a single identity and efficiently discovers relationships between identities that share certain characteristics like devices, IP addresses, or behavioral patterns. When a freeloader creates account #5, Dregs automatically links it back to accounts #1 through #4.
Example: Catching a Serial Freeloader
Here's what it looks like in practice:
No manual review needed... the repeat freeloader is flagged within seconds of signing up.
Actually Stopping Free Trial Abuse
Detection is only half the story. How you respond is up to you. Here are a few of the options that Dregs enables, unlocking fully automated abuse prevention.
Shadow banning
Let the freeloader sign up, but quietly degrade key features. They waste time on a product that no longer works for them, and eventually give up. It's not even obvious that you caught them!
Extra verification
Trigger an additional verification step (phone number, payment method) for users with low Uniqueness scores. Legitimate users pass easily. Freeloaders often give up with the extra friction.
Account blocking
Reject or disable the account outright. Straightforward, but it tells the abuser exactly what happened and feels a bit confrontational, so they might try to be sneakier next time.
Usage rate limits
Allow the account to continue, but throttle access to the features they're abusing. They get a degraded experience without a clear explanation and eventually go away on their own.
With Dregs webhooks, any of these responses can be fully automated. Your application receives the scores and badges in real time and acts on them without human intervention — even at 3 AM, even on holidays, even when your team is heads-down on a product launch.
