Pocket Blacklist

[EntityZero]

Hello,

I've searched for numerous hours trying to find information on this but to no avail. Currently people can pocket keypads and use them to crash the server. I've tried adding it to the GM.Config.PocketBlacklist but only to fail. I have added multiple different instances of the keypad I could think of but nothing, not even an error.
(This is in the garrysmod/addons/darkrpmodification/lua/darkrp_config/settings.lua file)

I am also quite inexperienced with lua so if you would please explain it thoroughly, thanks in advance!
