Just about every forum I've ever registered on has had a rules page you have to read before you can become a member. Surely HLP has one. Or had?
Aside: prospective forum members are complete strangers; why would you be inviting a complete stranger to dinner? Or has the way new member registration works really changed that much since 2006?
From the registration form, which is followed with a large "I accept the terms of the agreement" button, before a nick and associated info is entered (emphasis mine):
You agree, through your use of this forum, that you will not post any material which is false, defamatory, inaccurate, abusive, vulgar, hateful, harassing, obscene, profane, sexually oriented, threatening, invasive of a person's privacy, adult material, or otherwise in violation of any International or United States Federal law. You also agree not to post any copyrighted material unless you own the copyright or you have written consent from the owner of the copyrighted material. Spam, flooding, advertisements, chain letters, pyramid schemes, and solicitations are also forbidden on this forum.
Note that it is impossible for the staff or the owners of this forum to confirm the validity of posts. Please remember that we do not actively monitor the posted messages, and as such, are not responsible for the content contained within. We do not warrant the accuracy, completeness, or usefulness of any information presented. The posted messages express the views of the author, and not necessarily the views of this forum, its staff, its subsidiaries, or this forum's owner. Anyone who feels that a posted message is objectionable is encouraged to notify an administrator or moderator of this forum immediately. The staff and the owner of this forum reserve the right to remove objectionable content, within a reasonable time frame, if they determine that removal is necessary. This is a manual process, however, please realize that they may not be able to remove or edit particular messages immediately. This policy applies to member profile information as well.
You remain solely responsible for the content of your posted messages. Furthermore, you agree to indemnify and hold harmless the owners of this forum, any related websites to this forum, its staff, and its subsidiaries. The owners of this forum also reserve the right to reveal your identity (or any other related information collected on this service) in the event of a formal complaint or legal action arising from any situation caused by your use of this forum.
You have the ability, as you register, to choose your username. We advise that you keep the name appropriate. With this user account you are about to register, you agree to never give your password out to another person except an administrator, for your protection and for validity reasons. You also agree to NEVER use another person's account for any reason. We also HIGHLY recommend you use a complex and unique password for your account, to prevent account theft.
After you register and login to this forum, you will be able to fill out a detailed profile. It is your responsibility to present clean and accurate information. Any information the forum owner or staff determines to be inaccurate or vulgar in nature will be removed, with or without prior notice. Appropriate sanctions may be applicable.
Please note that with each post, your IP address is recorded, in the event that you need to be banned from this forum or your ISP contacted. This will only happen in the event of a major violation of this agreement.
Also note that the software places a cookie, a text file containing bits of information (such as your username and password), in your browser's cache. This is ONLY used to keep you logged in/out. The software does not collect or send any other form of information to your computer.
While I deal with the back end more than anything, which is why I didn't really contribute much to the discussion when the referenced guidelines were being drafted, I do try to keep somewhat up to date with the community (call me Sir Lurks-a-lot).
Might I point at the rules for the penny-arcade forum for a comparison?

On Rules Lawyering
These rules are not complete and are not intended to be. These forums are privately owned and the administration reserves the right to refuse service to anyone for any reason at any time. The excuse “but there's no rule about it!” will never be accepted as an excuse for bad behaviour. It is expected that all users are intelligent and mature enough. While we strive to be fair in the moderation of these boards, said enforcement is subjective by its very nature. Please see the FAQ below for information on what to do if you feel you have been treated unfairly.
This, I believe, is what scotty is trying to get rid of. From some of the discussions I have seen, this is one of the bigger issues that many have noted and have been 'bound' by, preventing them from taking action.
Also:
Users are expected to have a reasonable level of social intuition regarding what is and is not acceptable social behaviour, and you should avoid saying anything to someone on these forums that you would not be willing to say to them if they were a) standing in front of you b) considerably bigger than you and holding a club.
The decision on what is and is not considered Being A D*ck is determined by the mod staff. The defense “but I don't think I was being a d*ck” is not an acceptable one, nor is “but I didn't mean to be a d*ck”. Your message is what you communicate, not what you intend. That said, we understand that there is room for misunderstanding and interpretation in this rule and moderation staff will be open to polite and reasonable messages explaining why you do not feel an interpretation of this rule was fair.
Remember that we do not owe you an internet forum and that this forum is almost entirely run by volunteers.
Myself, I would suggest that those who are more involved in the community look at the linked URL and adopt as necessary. The PA community forums are some of the most drama-free and welcoming to new users I've seen anywhere, even with the occasional very heated debate (go look up some of the threads on how to deal with the overwhelming demand for PAX Prime tickets).
Soctty is a global mod, and has taken it upon himself to do something on his own that he feels is necessary to improve things. And so far, in all the notifications I've received on the thread (email notification BTW, I see it before it gets edited or otherwise folded, spindled, or removed) I've not seen one single mod or admin object to it.
You may as well get used to it, it seems that it's here to stay and probably be adopted by others.
