The rules as posted are really more ‘general guidelines of normal courtesy. If a new person violates them (or an old guy too) many times it is related to a troll or an advertising effort for a specific product or location. What we usually do is delete the post, and send a warning note via email making reference to the ‘read the rules’ comment.
If the violation is really gross and I am sure many of you have seen a few of them, we do a lock out after the deletion and then discuss it with the person if they inquire about it. Most usually just disappear.
For the vast majority of the membership the rules never are an issue.
I am sure, Felix, that there are lots of folks who, like you, have never considered the ‘structure’ of the website, you just enjoy what you like . Thats the way it should be. I wish that a few of the really nasty folks who show up now and then would do the same. This is a nice place with a lot of information flowing in all directions. Let’s All try to keep it that way.
