With this addon, you can declare a player in the raid/party as ninja looter.
If you upload your data and enough players declare the target player as ninja looter, the database will make a new entry with this name and realm as ninja looter.

If in future, a player with the name of a ninja looter declared player, comes into your raid or party, the addon will make a announce in chat that the specific player is a ninja looter.
Now you can choose if you go raiding with this guy or not.

The basic idea is from WC3-Banlist.
Thanks guys for this very usefull programm and the basic idea for this addon.
