Unfortunately no. People have suggested CryptoFuture to appoint mods to deal with the spam for months, I don't know why but Crypto didn't seem to be interested.
There are already users on chat, including myself, who have the power to globally mute other people such as spammers etc.
i did not see any Mod at the moment at diggit some players continuously spamming there, i like diggit with it's unique graphics and nice script.
there are jet apart from oldmate which I believe can globally mute, the other concern is that since they are not really a "mod", they spend some less time to monitor the chatroom, so some people still are annoyed by the spammers in chat, by actually appointing some people to take turn monitoring the chatroom, it will be a better option for now
