With many freemium services capping free accounts at single-digit numbers of users, "no limit" is a reasonable way to let people know that they can stop looking for the catch. It would be more confusing if they said "up to 5,000" users, which sends the wrong message about who their service is targeting.
Everyone understands that "unlimited breadsticks" implicitly means "lots and lots but not infinitely many"
Do you work for AT&T? Unlimited means unlimited. If there are limits, they need to be disclosed in advance. Especially if you are explicitly claiming that there are no limits..
That's a crock. Please show me one other service that explicitly states "no limit" that actually has a hidden limit. The 10,000 message search limit makes it mostly unusable for groups in the 100s or even 10s so why even enforce the user limit?
www.hostgator.com - unlimited disk and bandwidth. Never truly unlimited.
They limit the types of content you can host (no media sites), they set inode limits (http://support.hostgator.com/articles/pre-sales-policies/rul...), they will suspend you if you use too much server resources. Pretty much anything to keep you from using "unlimited" resources.
There are a ton of other examples. I would check out www.webhostingtalk.com if you want to see all the issues with these type of hosts.
They do explain that other limits make it essentially impossible to actually utilize "unlimited disk/bandwidth". And they don't mention unlimited on the home page. But fair enough, you found one.
