Once again this is the same as Majorasmask's issue with this. We have better methods of detecting what is a "grief" and what isn't. Logs are helpful. A 3 day ban by my chart is No level reduction but by Xexos its only 5 levels. This is Bastion, Not Sanctum or Zeal, its time to stop living in the past and focus on the now.
5 Levels isn't much at the lower ends, so early on it wont hit you too hard, but as people level, and master.. like most of the repeat offenders now have by now, 5-20 levels is a LOT. Thats time you need to reinvest in leveling, and skills/HP/Mana you loose to contribute to PvP while you are weaker.
This would also put these people back into the world to look for Mobs for leveling and bring some (However not much) World PvP back.
Further yet, my suggestion was intended for people who have already specced, until a point their bans exceed a set number, where they will get progressively more harsh. Such as re-mastering your path, before resuming your spec, and paying 500c, after wiping your money. Things like that.
Your example was invalid for the punishment because it was a simple grief and a short ban.
If anything,
Danda could further revise the 6 ban example to be a punishment-level ban.
level 1-6 depending on how harshly you should be punished for what you did; and who you did it to. Such as a group of people or just one person. All factors taken into account it could go as far as a small grief here and there won't add up to much, but if it's continuous then the next ban is a level higher, and so on. If they don't take that seriously then skip a few more levels since they then have several less severe punishments and one say, level 4 punishment. Take it to a lvl 5, and 6, then permanent ban for repeat offenses.
There's no excuse in a setup like that to keep griefing peoples shit, at that point you're just trolling admins and playing stupid, making them look bad, and yourself.
That said, I don't agree with that entire example, and I feel it's too abusable, which is why I would like to see a linear ban system implemented, with brackets falling under each level depending on the offense.
Such as, pillar griefing/griefing someones house, just a few blocks, then replaced with cobble, would fall under level 1 ban. But if your first major offense was tearing down an entire town, then yeah, expect a 2-4 week long ban, and some effort on your part to get back to your original status in the game.
In the same breath, if you had a bunch of minor offenses, I would expect it to scale, yet I would also expect someone to be given a fair chance to replace the blocks they broke. If you came and griefed my wall, and I PE'd it. I would expect the admins to ask you if you were going to fix it. However, if say, several days ahd passed and you simply ignored the fact, I would expect a ban without questioning.
You should sear it into your mind, that this is a NO GRIEFING server. If you take someone elses things and break them, YOU ARE RESPONSIBLE for fixing it in a reasonable time. If your excuse is to logout and forget about it, then you have messed up. Before breaking into someones house through their wall and not replacing the objects you destroy, you should have asked yourself if you would have had time to fix it after. If you or a friend can't fix the damage in a reasonable time, then logout, and log back into the game when you have time to play. There is no VALID excuse for this unless you simply lost power, even then you should've been more careful, which is why the system I proposed scales up before you get a harsh ban. Finally, if you lost power, you have more important things to worry about than as Dsawemd mentioned, "A game".
