A couple of points need to be made here, I think.
First off, getting an infraction is NOT a punishment. Those infraction notices are warnings that an actual punishment is IMMINENT if those warnings are not heeded and the infractions be avoided in future posts. The infraction system is an excellent tool for the moderators to use for a number of reasons. One is that a clear record is kept of all of the infractions that any member make make here. Someone may feel that they have a "budget" of one profanity laced post per month, which most people would not be able to remember. The infraction system, however, DOES keep track of that and accumulates the infraction points accordingly. Also, it allows a convenient audit trail for my review in case there are any questions or concerns about the use of the infraction system. Mods are people just like you and I and can have bad days, bad weeks, or even a life that suddenly turns bad on them. It is in the best interests of this site that I try to keep close tabs on the actions my mods take so I can take steps to head off any problems that a mod may wind up creating for me and this site. It can happen, I am cognizant of that fact, and I will certainly try to stay on top of that issue.
On another line of thought, the issue of consistency of enforcement of the rules was brought up. Let's see, I just looked at the posting stats and it shows that 921 posts were made in the past 24 hours. So, let's see, we have 3 moderators here at this time, so I guess I should check with them to make sure they each read their allocation of 307 posts.

To you see how unrealistic that demand would be? And in like vein, can you see how inconsistency is inevitable simply because ALL posts will NOT be read here by the mods. Even if they were to be, the mods are not clones of some central requisite personality so that all decisions will be identical from all of the mods. So some will have personal backgrounds that may lead them to feel that something said in a post is a violation, whereas another may not thing that exact same way. That's just the way it is, and there is no way to make that any better. Even if there were only ONE mod reading and evaluating all the posts, this one person may be in one frame of mind while reading one post, then three days later read the same exact wording and be in a completely different frame of mind and react differently. That is just human nature.
On another topic, profanity. Sorry, but this will always have to be a gray area that cannot be put into a black and white definition. Even if I made an absolute list of words that are considered to be profanity, there are any number of ways to get around that, which would mean either that list would have to be continually updated with the work around words, or it would be soon abandoned once the futility of it was pointedly shown. Also, keep in mind that I tend to gear my sites more to adults then I do to children. I don't actively discourage them from coming to this site (FaunaClassifieds, however, has a filter to deny registrations from anyone under 13 years of age), I also will not particularly make much effort to keep it a PG-13 rating. The policing of the content filter allowed to be displayed on any person's browser will have to be at the browser level. To do so otherwise would make this site have to comply with so many conflicting requirements of individual viewers that the least common denominator effect would make it such that people will become afraid to post nearly anything for fear of offending someone and receiving an infraction because of it. So necessarily, such rules about profanity and the like will have to be gray area, at the discretion of the mods under my suggestions. I'm sorry, but I've been over this issue many times on FaunaClassifieds, and that is the only realistic way to deal with this. And if you combine this topic with the above about consistency in enforcement of the rules, I am certain you can see how difficult it will be trying to moderate a site with the amount of traffic this one is getting. All I can ask of the mods is to do their best with the enforcement of the rules. All I can ask of the membership is to do YOUR best to try to make their jobs easier. Otherwise if you burn them out, it may be tough to find replacements that are doing as well of a job as the current staff is doing.
Darn, I'm not going to proofread all that junk. Please excuse any disjointed sentences....
