Not disagreeing with you, but those rules could most likely have some decent reasoning behind them.
It’s a WoM Subreddit, tolerance for off-topic posts is not very common among Discourse or Reddit Communities I’ve been in, the only reason you’re complaining about it is because a large majority of the posts you make are usually off-topic, which I myself have no problem with, it’s just the tolerance for it is simply something this community is somewhat lucky to have, as it allows for more friendliness and community sense.
I may have to go back on my initial word that I don’t disagree with you, this rule makes utter perfect sense, if you’re lazy enough to not have muted #marketplace when WoM had a much larger player count, you probably would’ve gotten annoyed that there was such a large capacity of trading messages daily, almost flooding forums to some extent, which could’ve annoyed some users, fortunately for us, we can silence topics on our own accord if we deem no interest in them, but I’m pretty sure you cannot do that on Reddit. (Correct me if I’m wrong, I’ve barely used the site in comparison to other Social Media)
Same reason as for Rule 2, I don’t think I need to go into any more detail, just reread what is above.
This would sort of tie in to my criticism about your attitudes towards these rules, but if advertising we’re allowed on this Subreddit, imagine the amount of users constantly advertising their own media to do with WoM, hell, maybe not even WoM, it would flood the subreddit to such an extent that it’d be almost unbearable. The approval from somesort of authority on that rule is also perfectly reasonable, as it would allow for a steady rate of advertisement when deemed necessary.
Common stereotype which most individuals would deem to fit with reddit, well, what if I told you thatthe majority of a community does not speak for the minority, and that not every single person on one platform is deemed to be the same. It’s the same case here, you can have people who will not respect people (although moderation usually takes these actions into account more than most reddit moderators would, due to a much older target audience on that application), and those who most likely would, it’s basic human nature.
TL:DR: You’re misunderstanding the point of the regulations in place. (my long essays solo your verse)
