I always read the fine print haha!
So I have always read the ToS for every video game I ever purchased, any online game I ever played, forums, subscriptions, anything involving an electronic payment (whether automated/scheduled or not), "free trials" or similar, etc. I don't like surprises. If the terms seem to be somewhat open to interpretation, I assume worst case for me and best case for the other party just to be on the safe side. If that makes me uncomfortable due to possible risk, then I will not purchase or participate.
ASR seems pretty simple to me with regard to the rules. There are only a few contentious topics, and they've been spelled out pretty plainly time and again (and even there, it's not necessarily the topics themselves, but rather the way people tend to engage when discussing those topics). Beyond that, try to engage with the idea/topic and not the person where you are in disagreement, and I don't think you're likely to ever have an issue. There are plenty of members who 'disagree' with various aspects that are generally 'part of the culture' here at ASR, but the majority of them get along just fine, because they engage with other members in good faith, whereas the 'trolls' eventually 'out themselves' by showing clear bad faith in their posts.
You mention 'how to debate,' which in my view is perhaps not the best way to approach a forum such as this. If you are looking for debate, you might be (or might appear to be) in a confrontational mindset that puts you on a path that conflicts with the 'good order and community/collegiality' aspects that are important here. As is often pointed out, tone is difficult to convey via text, so even 'fun' debate can seem unduly argumentative/aggressive/hostile to other readers, even if that isn't your intent. If you approach the site with the goal of sharing/learning/conversing/entertaining, then I think you're unlikely to ever run into any issues with other members or with moderators.
I mostly 'lurk' and read for entertainment/enlightenment or to examine and understand what areas matter most to me and contribute most to my enjoyment of my music. The more I can correlate my knowledge and what I read with my experiences, the easier it is for me to get things right quickly and easily and with the least time/expense/aggravation, thus allowing me to get on with the important thing for me, the music itself.
Just my 2 cents, and back to lurking I go! haha!
