How to you prevent someone from getting a "new free trial period" by just creating a new login?
- by Clay Nichols
I am considering several options for the Trial version of our web app.
The one I favor the most is the classic trial period.
Of course, it's a LOT easier for someone to hack this system.
They can defeat the various methods of fingerprinting the user, thusly:
Browser cookie: Clear their cookies completely (or just for our site) or use a different device. Although Evercookie may help with the former.
Email address: Create a new login (with a new email address)
I'm going to monitor things for a while and just see how it goes. If it's a problem I'll consider requiring a credit card number matched to a name and billing zip code. Each such "ID constellation" would be considered one user. Someone could still have multiple credit card numbers but we could flag the same name+zipcode coming up again.
Are there any better ways to do this?
