My forum doesn't have rules, just like FP it's "Common sense. If you don't know, don't post."
Edited:
Find in JustHost's ToS where it says you will be throttled if you use excess amounts.
Sure.

Resource Usage
User may not:
Use 25% or more of system resources for longer than 90 seconds. There are numerous activities that could cause such problems; these include: CGI scripts, FTP, PHP, HTTP, etc.
Run stand-alone, unattended server-side processes at any point in time on the server. This includes any and all daemons, such as IRCD.
Run any type of web spider or indexer (including Google Cash / AdSpy) on shared servers.
Run any software that interfaces with an IRC (Internet Relay Chat) network.
Run any bit torrent application, tracker, or client. You may link to legal torrents off-site, but may not host or store them on our shared servers.
Participate in any file-sharing/peer-to-peer activities
Run any gaming servers such as counter-strike, half-life, battlefield1942, etc
Run cron entries with intervals of less than 15 minutes
When using PHP include functions for including a local file, include the local file rather than the URL. Instead of include("http://yourdomain.com/include.php") use include("include.php")
While our shared services are suitable for the bulk of our customers, there comes a time for some websites when they are better suited for a larger plan, which allows for more dedicated CPU and memory resources. We reserve the right, in our sole discretion, to discontinue service to any customer with a website or other hosted data that takes up more than 10% of the server resources and/or 10% of the server's CPU. This means that if your website is found to be utilizing more than 10% of the CPU and memory of the service, we reserve the right to take your site offline. If this becomes necessary, you can either upgrade your hosting package, or request a pro-rated refund of the amounts you have paid in advance for the services. Due to the severity of this, and our ability to act quickly to correct these situations to avoid server issues, we will do everything reasonably feasible to provide you with a warning prior to taking your site offline, but we accept no obligation to do so.

JustHost seems to have copied most of its ToS from http://www.hostgator.com/tos/tos.php
The limits JustHost sets are pretty understandable though. I mean, you can get your panties in a bunch about how it's false advertising, but you're very unlikely to hit the cap, and as long as you don't, you'll probably get quality service ("probably" because I never used JustHost. HostGator were my first host though, and the service was nice).
WebHostingPad are kind of silly though:

Unlimited Hosting Space and Bandwidth
All our hosting accounts do come with unlimited hosting space and bandwidth. But we start each account with a set limit but as you needs grow, simply contact us to request additional resources and we will increase it to whatever you need. This new plan allows us to create more efficient use of our servers and provide better, faster, and more efficient hosting for our customers. Please note hosting space is intended for hosting and not intended for but not limited to online backup, storage device for multimedia content such as, but not limited to, movies, music, photos, or other media. Any use of our hosting service in this manner will be considered a violation of our terms of use and will result in automatic suspension of the hosting account without any prior notification.

But we start each account with a set limit
CPU and Memory Limit
All accounts will be only allowed to use 10% of cpu and memory and can not exceed a session longer then 10 min. This includes all database uses, email, cron jobs, and any FTP sessions.
Damn those unlimited limits.
Any use of our hosting service [for multimedia content such as, but not limited to, movies, music, photos, or other media] will be considered a violation of our terms of use and will result in automatic suspension of the hosting account without any prior notification.
You better not upload photos to the server you hacker.
At least Dreamhost are honest about it:

I've heard from a certain Gold Member whom I used to talk to that DreamHost has lots of PHP features/modules/whatever the fuck disabled, but as far as I can tell DreamHost are pretty good.
I use InterServer myself, and while my server isn't terribly powerful (I have their cheapest dedi; it's more than worth the cash though), the support is fucking fantastic. You don't get a reboot panel, which is kind of silly, but if your server is having trouble (or if you fucked up (chmod 000 / cough cough)) they're very quick to fix the problem.
