In short, the only restriction on blocking is that it cannot violate the ToU. As long as the admin isn't violating the ToU, they are free to block for whatever reason; including no reason at all. That said, the context of the block can be taken into consideration when determining if the block violates ToU. For instance, lets say there is a new wiki with the founder and 100 other editors. If the founder blocks 1 of the editors for no reason, staff aren't likely to get involved. If, on the other hand, the founder blocks all 100 editors, then staff may interpret that as an attempt to have a private wiki which is a violation of ToU. In that case, the founder would be penalized and most (if not all) of the blocks revoked by staff. In the case of block warring, it depends on the details of the situation. In a case where user2 blocks user1 to retaliate for a justified block (or even for just a disagreement) and user1 has not contributed to the wiki, staff may choose to revoke the block.
