This is a self-explanatory script that will automate blocking the last tell or shout by adding the person to your blacklist.
The script uses Auto It. With the default key combos being;
Ctrl+Alt+Shift Delete = Block last /shout er
Ctrl+Alt+Shift Insert = Block last tell
Ctrl+Alt+Shift End = Terminate Script
All the delays for key sends are easliy customizable to suit your computer speed.
An obvious heads up, it is automation. So it *could* be construed as breaking the EULA, though I doubt they care if you are making blocking bots easier. Either way I take no responsibility for deleted accounts. On the up note I use it and I'm still in game.

As soon as addons are implemented I shall be making a 100% legit way of doing this.
