A recent experience with the app's internal keyboard has led to a concerning discovery. When utilizing the internal keyboard, I noticed that it is unable to register consecutive keystrokes of the same number. For instance, attempting to input three consecutive '8's is impossible. However, using an external keyboard, such as an iPad's, allows for seamless and continuous number input. With this newfound understanding, I proceeded to test the app's functionality by inputting a series of numbers and submitting the entry. To my surprise, I was met with a warning message indicating that I had been added to the app's blacklist and was subsequently barred from using the online services for a duration of three years. Furthermore, I found it noteworthy that the app did not provide any prior warnings or attempts to discourage this behavior. What's more, the usage of an external keyboard does not constitute a violation of the user agreement. I attempted to seek clarification from the customer support team, but their responses were vague and unhelpful. The incident has left me with more questions than answers, and I am left wondering about the logic behind such a stern punishment.categoryId:111111
