    Stop responding to grief and prevent it instead. Grief Prevention will solve your grief problems without a roster of trained administrators, without 10 different anti-grief plugins, and without disabling any standard game features. Because Grief Prevention teaches players for you, you won't have to publish a training manual or tutorial for players, or add explanatory signs to your world.

    Grief Prevention stops grief before it starts automatically without any effort from administrators, and with very little (self service) effort from players. Solve all your grief problems with a single anti grief download, no database, and (for most servers) no configuration customization.

    Awesome plugin! Just one question, is there a placeholder so that i can display the amount of claimblocks in the scoreboard?
  2. juniordeejay
    Version: 16.8
    good plugin, the best and most complete. If you could add that there was an option to be able to save schematics from the claimed regions it would be fine, so with the reboots of the worlds, the players would lose nothing. A command for once the world is restarted, those claims are regenerated. / adminregenschems for example

      That sounds like a neat feature, perfect for an addon!
  3. doggstar
    Version: 16.8
    i've looked a number of anti-grief plugins, this is by far the best especially with the ingame help. Thank you RoboMWM for continuing to maintain and improve.

    I agree with Grandof below, on the "separated players list (just a list of all players who are separated) and a softmuted players list (list of softmuted players)"

    also, i would like to see some more resolution on the "repeat messages" being muted, it seems to happen a lot. or at least to notify the poster that their messages are being muted.

    Thanks again!

    Easily the best anti-grief plugin. Only thing I wish is that there was a separated players list (just a list of all players who are separated) and a softmuted players list (list of softmuted players) that's all. Again such a great plugin very happy using it!

      Author's Response
      Yea, the softmute feature was hacked on by Big_Scary so he wouldn't have to worry about altering the database it seems. That, or so he didn't have to load PlayerData for ignored players. Not really sure which, but yea. Definitely looking into how to do this properly for version 20, though it'll likely be in an addon.

    Version: 16.8
    Based on the current version of this plugin I say 5 out of 5 stars for sure. I love the plugin and enjoy using it quite a bit. There are a few things I would love to see added to it to allow for players like me to have the protection but the ability to use it as a town creation plugin as well since towny is to difficult to use for basics.

    See the discussion page for my recomendations for what I think should be added to make the plugin even that much better.

      Author's Response
      Yea, GP, like other region protections, is designed to standalone/work as if it were the only region protection plugin. Addons are possible though to provide the desired compatibility you wish to achieve with other region protection plugins.

    Best plugin ever! A must for servers! Takes all the hard work out of trying to figure out who did what..simply make sure players know to claim their property and it's done! I love it 5 stars

      Author's Response
      thanks c:

      Big_Scary is the one to thank though especially for the "educating players how to claim" part. Definitely IMO one of the key features that many other plugins don't do.

    Version: 16.8
    Ottimo, semplice , basta fare /claim per avere una piccola parte di area protetta da click degli altri giocatori lo uso sul mio server survival
