I'll be posting on the subject of moderation on the internal some point soon. I do think this is something that the mods need to discuss with the admins. Getting a second, impartial opinion is a good idea though. I don't think I've banned anyone without getting a second opinion except when we instituting a zero tolerance policy on flaming. Back then it wasn't really necessary to check as calling someone an idiot got you banned.
At the same time, though, the phrase "necro'd!" gets thrown around by certain individuals far more often than it needs to (god i hate that beam kill it with fiyah), and there are instances when using a pre-existing thread is perfectly acceptable. For one, stickied threads are always open to new posts, and posting in a campaign's original release thread to comment on it is generally considered just fine too.
Agreed with on all points. I'm pretty sure I've had a go at people for overuse of the Necro beam in the past (I've had a go at people about every other beam for certain

). As with the calls to lock a topic or shouting "In B4 Lock" when used on those threads they're at best spam and at worst an attempt to tell the moderator to follow the herd rather than exercise their own judgement.
Again, if you want me to tell people off for misusing it more often, I'm happy to. With great power comes great responsibility and if you're wielding a beam cannon and not bothering to check your targets you're going to end up facing a court martial soon enough.

What about this? http://www.hard-light.net/forums/index.php?topic=73625.0
So you have at least four persons permabanned from GenDisc. That actually seems like a lot to me, compared to other forums where I go.
1. No 4 users is not particularly high. Most forums have people banned. Take a look at The Escapist forums for instance and try to find a single thread that doesn't have someone banned on it.

Furthermore Political Prisoners isn't even a real ban. They can post anywhere else in the forum, they just can't post in the forum that brings out the worst in them.
2. The examples you give weren't even perma-bans. In fact they were punishments for abusing HLP's broken permissions system during the upgrade to give themselves image sigs and lasted all of 2 days. Before I gave you those stats I looked up the actual numbers (something only an admin can do easily).
Now, about High Max, I've yet to see the reason why he was banned. He was a bit quick to anger, but in my experience he was just as quick to calm down. Maybe he wasn't the brightest member out there, but I still don't know why he was outright banned.
High Max was a massive disruptive influence on the forum. No matter the subject he would always steer the conversation round to discussions about his belief that he West was morally bankrupt while the Orient was good and pure. He would then condescendingly argue with anyone who disagreed with that view completely derailing the topic.
This is a great example of why he was banned. In one thread he asks for heavier moderation, claims he is a model forumite, posts a long, off-topic steam of conciousness type post, gets into a flame war and then deletes all his posts on the subject making the thread incomprehensible.
There are more examples but he wiped almost all of his posts after being monkeyed and was then banned.
Shall I point out that he was monkeyed at least 3 times (that are mentioned in the admin forum, it's undoubtedly a lot more) and warned repeatedly. We put up with this sort of behaviour from him for years! So it's not like he was banned for nothing. It a long-term pattern of abuse that got him banned.
About Liberator, again, not the brightest member, but I'm still under the impression he got prisoned just because he was right-winger. I mean, yes, he was stubborn, and he couldn't articulate a reasonable argument even if his life depended on it, but I feel, based on my experience here, that If he would have been a left-winger, there would have been more tolerance for him. Note that I'm not saying this because I liked him, since he seemed to have a really bad opinion about Latin Americans, almost bordering on xenophobia.
Actually Kosh has been very left wing for the most part and you can see how close he's teetering on the brink of getting banned (admittedly non-perm at the moment). Iamzack is another example of a left winger who has had trouble with the admins.
Liberator was banned, not for his opinions, but for his inability to actually debate. He'd post something that would get everyone seething, get replied to, ignore the replies and just post something else. If this behaviour is intentional you'd call it trolling. In Liberator it may have not been intentional but it was just as disruptive. He was told several times how to avoid being a problem and he completely ignored it, continuing the same pattern of behaviour.
After repeated temp bans it was simply made permanent because it was too much trouble to clean up after him.
Charismatic?
Banned for a week for trolling the Leslie Nielson RIP thread. Wasn't permanent.
Trashman, as far as I know, was prisoned because he gratuitously insulted another member whom he was having a heated argument with. I remember reading those particular posts long ago. I have no objection against this sanction.
It wasn't just that. That was simply one in a long string of offences.
Telling someone to kill themselves because they disagreed with him wasn't even the last straw. I forget what finally got him banned but it was more of the same.
