The latest wording was:
..to which Lensman commented:
I know that the wording of that unlimited policy has been under review, and I don't think it is "quite right" yet - the folks who are working on this are finding it difficult to convey the desired meaning in the "simplest" terms.
Note that "friends and family" are very different than "the general public" - DreamHost has no problem with your using the "unlimited" accounts to host friends, clients, family, etc (whether for free, or for "reselling") - what they are tying to prohibit is just turning your resources over to another without control or obligation - like in running your own "webhost" by reselling "unlimited" space. This is a somewhat "common" abuse of our systems by those in some countries from where our it might be difficult for some to legitimately obtain a DreamHost account due to our fraud checks, payment methods, etc.
If it is your client (in the sense that there is real value added, other than just saying, "He's my 'client' because I host his sites"), your friend (in a sense more reasonable than "Everyone is my friend"), or your family member ("If he puts warez up there I'll beat him severely ... and I know where he lives!"), then you are welcome to do that on unlimited accounts.
None of those three scenarios were meant to be included in the definition of "the general public"!
