You have a point.
I would argue that the devs have broken the rules too - namely, changing the so-called 'final' stakeholder list.
That's just as much 'breaking the rules' as owning more than 1 account is.

the rules about how many stakes are allowed are more important to the rule of not changing the stake holder list.
just like the the rule where i live that police do not carry guns.. if the people took arms in a civil war between the east and west would the police not arm themselves to put an end to it? some rules are supposed to be broken under certain circumstances.. this being one of them.
If this particular rule is so important then can I ask why those with NEMStake tokens on the NXT AE are permitted to have more than 1 stake? Doesn't really add up.
The only thing this last-minute sock-hunt will do is make a few people very, very unhappy without really benefiting NEM in the process.
