    With this plugin you can block much more commands and also the tab completion. I hope I could help you.

    The latest version works for 1.7.9+. I use it myself on my 1.7.10 server.

    Dev build #37 has been built from the changes here. I downloaded Essentials and was able to tab complete a player's name with /msg <name> and a few other commands (the account was deopped). If anyone knows of an instance where this isn't the case, let me know please.
