How confident in that are you? Look, for instance, at the vast gulf between Reddit's TOS and what admins enforce. Or even "enforced" four or five years ago when Reddit was still small enough to conceivably be policed in such a manner.
Are you? Maybe while Hubski is still small the admins will be able to ban people breaking the rules easily and quickly, but as the site expands so will the number of TOS breakers and eventually it will become impossible to moderate and enforce that section of the TOS.
