Moderator Guidelines
Moderator Guidelines
- Don’t be mean to users. Be gentle or neutral.
- Most moderator actions which have a modlog message should include your username.
- When in doubt about whether or not a user is problematic, send them a DM.
- Don’t waste time debating/arguing with problematic users.
- Assume the best, but don’t tolerate sealioning/just asking questions/concern trolling.
- Ask another mod to take over cases you struggle with, if you get tired, or when things get personal.
- Ask the other mods for advice when things get complicated.
- Share everything you do in the mod matrix, both so several mods aren't unknowingly handling the same issues, but also so you can receive feedback on what you intend to do.
- Don't rush mod actions. If a case doesn't need to be handled right away, consider taking a short break before getting to it. This is to say, cool down and make room for feedback.
- Don’t perform too much moderation in the comments, except if you want a verdict to be public or to ask people to dial a convo down/stop. Single comment warnings are okay.
- Send users concise DMs about verdicts about them, such as bans etc, except in cases where it is clear we don’t want them at all, such as obvious transphobes. No need to notify someone they haven’t been banned of course.
- Explain to a user why their behavior is problematic and how it is distressing others rather than engage with whatever they are saying. Ask them to avoid this in the future and send them packing if they do not comply.
- First warn users, then temp ban them, then finally perma ban them when they break the rules or act inappropriately. Skip steps if necessary.
- Use neutral statements like “this statement can be considered transphobic” rather than “you are being transphobic”.
- No large decisions or actions without community input (polls or meta posts f.ex.).
- Large internal decisions (such as ousting a mod) might require a vote, needing more than 50% of the votes to pass. Also consider asking the community for feedback.
- Remember you are a voluntary moderator. You don’t get paid. Take a break when you need one. Perhaps ask another moderator to step in if necessary.

I wonder at what point repairs would be satisfactory for engineers to declare it usable again. Would it need to go on an empty test flight exactly along its normal path? What's the minimum incurred damage at which a plane would be considered totaled?
There are ways to non-destructively test for cracks and voids in various structural elements. Planes already go through very stringent inspection and maintenance cycles so various physical factors will already have a well-established baseline to compare to.
Some speculation; the damage may be far less than you'd think. Aircraft are (generally) designed to fail gracefully and the front landing gear is a mechanism that sees a lot of force during landing. I can't tell if the assembly folds back into the landing gear bay or if it penetrates the fuselage without collapsing.
A whole sack of shit went wrong if the fuselage fell directly onto the gear assembly but if the landing gear "simply" folded back into the bay it could be a relatively easy repair. Airframe loading is extremely well-characterized and engineers are already running the numbers on what forces went where.
All that said; fuck McDonnell-Douglas. Boeing "acquired" them back in the 90s. Somehow the MDD board of directors (comprised of businessmen) took over leadership roles formerly held by people with engineering backgrounds. A lot of the failures and poor reputation Boeing has suffered in the past few decades are very likely related to that leadership change.
It sure looks like the nose gear rolled forward as the fuselage falls. Which direction does it fold up, wheels fore or aft?
Judging from pictures it does appear to retract forward. Makes sense to me considering the forces the landing gear would experience. If the hydraulic deployment mechanism were to fail midair you can still manually deploy it from the cockpit and it will fall and lock into place.
Hmm, yeah, that makes sense because if it folded backwards, well, if the plane were landing with more force than expected...!
I'm no expert, but as I understand it a damaged plane has to undergo very extensive inspection and testing of anything that could potentially be damaged before flying again. A single test flight says very little about safety, other than that it happened to work once, and would not be anywhere close to sufficient by itself.
"totaled" has a technical definition: it's assessed more expensive to repair than to replace. That will include the cost of all the testing.
I have no idea what this will have damaged. Aircraft can be put back into service after some pretty serious damage, but you make a good point that tests on the structure of an aircraft are done on a new one, so you can't just do a single test and job done to get the same level of confidence that everything's ok - if something were weakened, it wouldn't be clear when it might fail.
