Login Checker? (Twitters, Instagrams, ect)

Hey everyone, I was thinking about coding a new product. This product will be a Login checker. So lets say you have a list of "usernamesasswords" in a text document. Here is an example of how it would look..

Username1assword1
Username2assword2
Username3assword3

You would import into the program, and begin checking to see which accounts work and which does not.

You could find these types of dumps somewhere on pastebin.

how much should I sell a product like this for?

Lemme know guys

Thanks!

It would be cooler if you can just type in a username, and then implement a list of common passwords and see if the passwords will work with the username.

I could probably make a separate product like this as well. Thanks for the suggestion.
