I have my tricks to find judgmental or offensive opinions or comments... just running through the questions and judge which ones were likely to attract them! Anything about religions, race, or "delicate" properties of a person would get "shoot with sharp" opinions.
Each week I'd find 2 or 3 opinions attacking either black people, or homosexuals, muslims, jews,... and hide them immediately. One or another way, recently my moderation turned to 80 to 90% questions. Rarely an opinion and I think the reason is the number of questions likely to trigger "wrong" opinions has decreased.
I think unless the question is blatantly racist or something it should be allowed to be asked. For example I'm Christian but I don't have issue with atheists asking questions that disagree with my opinion so long as it isn't something like "ll christians should die" or something like that. If this website gets too much censorship it will lose it's appeal and value fast. Its better just to remove the offensive comments in my opinion.
It is other way around for me because the quantity of mods has been considerably increased and questions can easily be seen in the site feed (while in case of opinions and comments, you need to open each thread) so other mods can see them easily as compared to opinions/comments.
Being a senior moderator, I've better understanding of what should be hidden. I spend my time scrutinizing opinions and comments and surprisingly, I find a lot of negative posts 'on which' a lot of mod have already submitted their opinions on. It means that newly selected mods don't have that better understanding or knowledge.
I'm not that active as I used to be so, it's difficult for me to find questions in an instant.
I don't know I feel like it's about 50/50. Like, I usually browse from Most Recent so I catch a lot of questions. I also follow questions that are likely to have offensive posts and people who have a tendency to misbehave so I pick up comments that way. Plus there's just the random things you come across and what people link and tag you to.
There is a lot less for us then there used to be though. When I started there were like 30 mods. Now there's like 70.
I can only hide opinions or opinion comments. But even before I was a mod, I usually only report questions because I'm one hella lazy fellow to go through opinions or comments to see if its worth reporting. I can find at least 3-5 questions to report each day lol (I'm basically on here all day whole weekends so yeahh)
I think the number of opinions that need hiding has gone down. I think there is less offensive opinions on here at the moment so I think I will find myself hiding more questions as a result of this. I always stop and think before hiding something rather than go at it like a bull at a gate.
I am an ex mod (resigned) but I agree with your theory but then again I think people usage style has changed- I no longer go near feeds, I just basically staying in topics I like Fashion & Style, GaG Community, How Do I Look and Other - When I was a mod (early summer) I reported/hid 1 or 2 things a day now I report a couple of times a week on as you say mainly questions.
