The same can be done for selling an item? you can /smsmute or /ignore the player for such cases as you said? isn't it?
I'm pretty sure this won't require a really complicated scripting as a similar script already exists for Selling the item.
I wont change my statement.
This seems rather useless than anything.
How would this benefit me as a player?
We have several features in the game to avoid players who is asking for money, etc.
You can avoid a player by using the features implemented by the server.
Whether or not it's a simple script does not showcase if the suggestion is useful or not.
