I use a Rage bot in every group that I own/admin in and it's used in so many others that I'm a standard member of. I couldn't not jump on the opportunity to have the privilege of using a Premium Rage once it became available.
I donated into the Premium Rage project because I could see the creators vision of it. The current set of features that I use most are the Disallow Spam, Censor Anyword, Disallow Noobs, and set goodbye.
Disallowing the spam has cleaned up a lot of unnecessary page fill that some members do out of boredom or spite. Censoring is a very useful tool to keep groups truly clean of curse words, or other standard annoyances spoken by new members. Disallowing Noobs has proven to be a useful tool to remove new kiks who tend to be the most volatile within a group. Setting the goodbye message is honestly just used for entertainment in my groups. Depending on what you set it to say, it can be a rather good way to start a conversation.
There are other features that are currently in beta testing and I'm very excited to be able to implement them once the tests have proven successful.
