For more than a year, we have been battling persistent spam sign-ups. They've easy to spot, as they're only created with bogus email addresses on the aol.com, gmail.com, hotmail.com, outlook.com, and yahoo.com domains, and almost always have 3 numeric digits embedded in the email prefix. Most recently, we've also been getting accounts created with a first name only with the city/state always being Toronto, Canada. Still, removing them takes a lot of manual labor to manage. Florence was extremely helpful in explaining the differences in each setting, making several recommendations for keeping the bots and fraudsters away.

Just set up, excited to see how it goes, getting 20k bots a day from China on our site. Super helpful on the set up, will report back once we've used this for a few days.

Lina was incredibly helpful and patient throughout the entire setup process. She clearly understood my use case, explained everything step by step, and even tested the rule herself to make sure it worked as expected. Her support was fast, clear, and very professional. Truly a great experience — highly appreciated!

Great app, and great customer service. Works well and was able to immediately stop bot orders on our site! Edit: The bots have continued but customer service has been very helpful in finding other parameters to help stop it.

Set up was quick and straight forward. We are able to block visitors based on ip of fraudulent users, and block checkout based on a variety of parameters. We can also witelist users if we choose to. The support is great, they quickly route you to a human support person, and don't waste your time with an AI widget who can't fully understand your question. Each person I've engaged with gave us clear recommendations on optimizations to make based on our needs and suspicious activity. Delivers great value, would definitely recommend.

I just installed this app so I don't have longterm experience, but Sophia was a total rockstar in using her VPN to show me that the app was working from various countries. Super fast and friendly. Give Sophia a raise! :)
