I'm the head moderator. We have a guideline that the least moderation is the best moderation. The almost best we can do is have some people think we over moderate and some people think that we under moderate. At that point we will strive to get better. The super users primarily help the moderation staff by temporarily moderating posts (which submits them for moderator review). Giving them extra privileges (e.g. longer time to edit their own posts) is the only compensation (besides our thanks) that they get. The moderation team is all volunteer, except for me. My pay is about minimum wage according to my contract and under $2/hr according to the time I really spend. My observation is that the crap to thanks ratio for moderators is about 10 to 1. Normal moderation tasks are hard enough to do "right". We already make enough mistakes doing that. In theory it is possible to eliminate all posts someone has made. In practice, as a policy, it would require more work than we have available resources. That's why, as a policy, we don't offer this service.
As Sib has stated, we have time limits on editing and deleting your own posts. This is because we've had people abuse the privilege as a form of trolling. We could have chosen to simply ban people who abuse the privilege, but catching such acts and proving them is labor intensive. We're damned if we do and damned if we don't. Everyone (except new people with less than x posts?) can edit and delete their own posts for a short period of time (I'm not sure of the exact limit - my guess is about 15 min to an hour). Super users and moderators have different limits because we can be trusted and this approach minimizes moderation effort.
With respect to locking threads, we don't like to do it (least moderation is best moderation). In general we won't do it unless a thread has gone on for many pages, we've given a chance for cooler heads to prevail and there are several different posters who are "in the fray". It's a shame that a few rotten apples spoil it for everyone else, but if we have to ban everyone who gets a little bad now and then, then I'll start with banning myself. We have a limited number of tools available to help keep the site spam free, relatively civil and even friendly. We try to be flexible in choosing the right approach for each unique situation. That opens us up to accusations of having double standards, but it's a choice we've made to try to minimize the moderation that we do. That's not because we're cheap and trying to save money. It's because we believe this approach is best for the community. If anyone takes exception to specific instances of moderation, they can appeal the action to Tyler (the site manager). These are not things I've made up. These practices have been handed down from the folks who started the site via several generations of moderators.
Although this site is currently owned by a corporate overlord (Vail), our marching orders from day 1 have been to continue on with no editorial changes. Vail gets no different treatment here than Aspen, Stockli, Under Armour or any other ski industry corporation. Yes we try to be friends with the industry. We're in this to create win win scenarios for everyone we can. Anyone can say a specific resort "sucks" here on Epic. They are entitled to their opinion. But if someone backs up that opinion with facts that are grossly in error, they are likely to get their post moderated regardless of who they are disparaging and especially so if we determine there was malice aforethought. These usually aren't easy calls to make and we don't make them lightly.
I realize none of this explanation will make your experience here any better, You've got a right to walk away and we're sorry we could not provide a better experience for you. Most people find that they get more than what they've paid for. There are limits to free speech. You can get arrested for yelling FIRE in a crowded theater. EpicSki was started as an attempt to create an online equivalent of the apres-ski bar. Every bar has an atmosphere they try to create and maintain that won't necessarily appeal to everyone and is necessarily more restrictive than "free speech".
At this point I can only bid you adieu and wish good snow for you.
