100% better coded than this shit.

ECProtection is a newly developed tool to protect against griefers.
This protects Chests, Furnaces, Doors, Signs etc. from being destroyed by others than the owner of these "blocks".
However this uses very little ram and saves most to a database located inside your plugin.yml folder.

PLEASE USE A VERSION AFTER V2.7 to fix a bug i accidently made in PlayerInteractionEvent. V2.4 or V2.8+ between please dont use them

Permissions (Added in V2.0 : Fully working in V2.4 : In V2.0 - V2.3 only ops have full permissions):
ecprot.normalUser : Allows user to place chests, use /ecp command and /ecp friend <list/add/remove> <null/name>
ecprot.adminUser : Gives full access to everything in the plugin. All command ecp, permissons etc..

ecprot.bypass : Allows players to use /ecp bypass
ecprot.use : Allows players to use the /ecp command
ecprot.use.friend.list : Allows player to use the /ecp friend list
ecprot.use.friend.add : Allows player to use the /ecp friend add

Info:

Friendlist:
Friendlist stores your friends added to your friendlist in the database. They can be added and removed with commands.

Updates:
Updates will get pushed as soon as i realize there is a glitch or there are new content added.
In version 2.7+ you will get notified when a new update is available. This is an example.

Commands:
/ecp help : For full list of commands.
/ecp friend add <Name> : Allow others to interact with your protected blocks.
/ecp friend del <Name> : Remove someone from your friendlist

Config (Added in V2.5):
