Remzak mostly has it right but I'm going to offer some additional clarity. Your ISP has terms of service, which stipulates that if you act in a way that violates their terms of service, they can cease to provide you with their service. Here are some things that ISPs say they can suspend your service for doing:

• Send spam or bulk email
• Send viruses/malware/etc. to other users
• Engage in illegal activity
• Transmit content that violates copyright law (basically, pirating)

If one violates a term of their service provider on this forum, it's within the rights of the administrators to tell one's ISP and let them do what they will with that information.

OK, now just one second here, none of those have to do with any of the rules on the forum. I understand and comply with the rules here and as well as my ISP, and i'm not breaking any laws... I aslo feel its a D*ck move to just go crying to someone's ISP for trollers... seems a bit extreme, whatever. 

My rights don't end where your feelings begin.

this is honest feedback. why should i give you my time and energy... or hell money if you Illegally threaten to shut down a service of mine?

"If you break any of the above rules, the NerfHaven staff can, and very likely will, delete your account with little or no warning. If you repeatedly troll or spam on this forum, this activity will be reported to your ISP as harassment, and may result in the termination of your internet access."

​Just making sure here, if a admin could please clarify... How is this legal? and how do you plan on shutting down MY internet? I pay good money for internet access, for a service they provide ME and I can do what I want with it within the laws of my country. I have common sense and I am wize to the ways of the internet scammers out there. how do i know NerfHaven isn't a scam?

First impressions are not very good of this website... most of the do-not's are just common sense. and it seems as though the admins are real pricks here. I came here looking for a nerf war in my town before winter... not to get banned and my facebook rep hurt. just look at all these rules. I mean... common sense people! heck some of these are stupid... like WTF.

• DO NOT Post in threads that have been inactive for more than a few of weeks, unless you have a really good reason. (Even then, probably better to post a new thread)
• DO NOT Post like you're in a chat room or sending a text message. (ie don't post ' u r a noob lol  ')
• DO NOT Double post. Use the edit button if you need to add something, instead of posting twice in a row in the same thread.
• DO NOT Post a 'which is best' thread, a 'what mods should I do to my [blaster]' thread, etc. Read the forums, make your own decision.
• DO NOT Post Memes. Only Groove is allowed to post humorous images with embedded text, and photos of barely literate felines.
• DO NOT De-rail a thread, drag the thread off topic, or get into a pointless argument.
• DO NOT Post just to promote your nerf website or product. Especially do not plug a non-nerf site.
• DO NOT back seat moderate. If you think someone is breaking the rules, use the report button in the bottom left corner of posts to report it to an admin (this feature only available to full members). If someone asked a question that could've been answered with a quick search, feel free to help them out and link them to the information.
• DO NOT post from your cell phone/tablet unless you can do so with the same level of quality you can when using a computer. Posts with poor quality or bad grammar will not be excused because you are posting from a phone.  Don't say, "I'll add photos when I get home", wait until you get home to post in the first place.
• DO NOT try to buy/sell anything outside of the trading forum. If your account doesn't have permission to post in the Trading forum, that means you haven't earned the privilege to buy/sell on the site yet.  This is not an excuse to post about buying/selling in other forums.
• DO NOT Post in the Off-Topic forum unless you can follow These Guidelines.
• DO NOT use obnoxious formatting (colors, bolded text, fonts, large text) unless it is necessary to make your post clear. These tags exist for conveying information and emphasis, not for artistic expression. See the Style Guide for details if you are not sure.
• DO NOT post video-only content. Include photos and text in your posts.

I really hope you guys get shut down or DDoS again!
 
Thanks for your input!
