1. How would you deal with a user who produced a steady stream of valuable answers, but tends to generate a large number of arguments/flags from comments?

I would check every one of their answers like its a brand new user. You can post good answers, that doesn't mean that all your answers are perfect and good.

2. How would you handle a situation where another mod closed/deleted/etc. a question that you feel shouldn’t have been?

Open a post on Meta where we can discuss. The line of what is off-topic can be blurry at times, and we all have a different line at which we declare something is out of bounds.

3. A fellow moderator takes an action the community disagrees with, and the community takes it to meta. You also disagree with the moderator's decision. What do you do?

Before taking sides publicly, I would chat with other moderators in the moderator private chat, or a private channel of some kind. See who is the outlier. Him or me. And also be able to take a stance as a team instead of all going in our own direction.

4. What would you do if you were the moderator who took action the community disagreed with in the situation described in question 3?

When I screw up I have a simple mentality. See where I screwed up, what can I learn from it to not screw up again. I would take a look at how I approached things, maybe poke around with other mods see how I tripped up and try to not do the screw-up again.

5. You (a moderator) and another community member both answer a question on the main site. The other answer is well written but (objectively) incorrect, and has gathered a similar amount of upvotes to yours. What do you do?

I would comment on their answer to try to figure out how they got to their conclusion. Sometimes memory can be a fickle thing and you are certain you remember it being one way when its clearly another.

So by challenging their answer, pointing out proof that something is not exactly right or things that do not align thats a way where they can modify their answer and put something down that is right.

6. Which moderation tool do you use most often during your average day on Arqade? Which do you use least often? Do you see that changing in case you get elected?

I don't often use the editing function of a post. English is not my first language, so as long as its not obviously completely wrong, I don't touch it.

Modifying a sentence is hard because you don't want to change what the person meant either.

So I don't really use it. And I would not plan in 'using it more'. I'm moire about closing really bad questions than try to doctor them to have a decent question.

7. Moderators are not selected because they are domain experts in certain tags, but it so happens that you are an expert in one such tag. You see that several members of the community have elected to close a question as a duplicate, but you see that the duplicates don't actually answer the question as stated, nor do they provide a useful signpost for the asker. How do you proceed?

Debate with the closers in the comments about how the question might look at asking the same thing, but are actually asking for different things. If the closers do not relent, I would check with other online moderators see if I'm the outlier or not. If I'm alone or not the outlier, I would comment why I think its not a duplicate and protect the question from other close votes (I think mods can do so? Not certain.)

8. There is a high-rep user who is very active on the site, but frequently uses strong language which violates the Code of Conduct in their comments. When you warned them, they replied stating that the questions are of low quality which is why they left those comments. They also threatened to quit the site. Despite the warning, they continue to post similar comments. What steps, if any, will you take in order to address this situation? What if the comments were on Meta instead of main? Does that change your approach at all?

1- Warning.

2- If warning is not heeded and continues, see for a ban. Temporary at first, and if he continues move towards permanent. (24h, 7 days, permanent)

3- If he threatens to leave the site... well ciao. We do not want toxic members in here and if you are toxic and want to leave, we won't stop you.

9. In your opinion, what do moderators do?

Make sure the cogs are oiled and this machine works well. Even if this is a big ship, pilot it to be a great community based on respect and getting the information you need.

Without someone in charge like a mod, that ship would have no direction and could quickly go crash in the reefs.

10. A diamond will be attached to everything you say and have said in the past, including questions, answers and comments. Everything you will do will be seen under a different light. How do you feel about that?

In 10 years of posting, I don't think I have a lot of things that could be taken out of context or that have aged poorly.

I usually am more of a middle of the road, see both sides kind of guy. And that, I think, makes that I don't do much takes that can be shown as 'a horrible take' a few years later.
