Minecraft Username:person13

Brief Description: I sent a payment to a player named mattf26 by typing /pay matt 400 but the payment was sent twice; once to mattf26, once to matthew_gruber. Apparently, if a player sends money to a user but does not type the full username, then the money will be sent to more than one user.

Instructions: Find a group of players with a similar phrasing in their name, as little as two letters, and send money addressed to that phrase.

How many times did you recreate this bug?: 5 times, 3 are screenshotted below.

Result: The money was sent to multiple users, draining the cost of each payment from my balance.

Expected Result: I expected it would either send the money to the correct user, or send the standard message of either "Player Not Found," or "You need to specify a player to pay."

Well, is there a way of eliminating the "pay the price" part? Perhaps by narrowing down how specific the username needs to be. Making it a requirement for players to type out a full username to send a payment seems like an alternative. I think this would take care of a lot of inconvenience in the future, as well as random 0.01 spam payments I tend to see in chat, like the ones I caused.
