this applies to all, not pool hoppers alone. the correct term should be addresshopper not pool hopper. the problem is that maxpps creates staying dept.
with prop u work for eligius, this creates dept too, but that is paid every 1btc and fully after one week of inactivity.
with maxpps the dept stays because it's not fully paid out because of the limiting value, and accumulates with every new address. so there needs to be a way that this dept is paid.
u can then implement rules like 1month of inactivity of the address voids the dept(poolowner gets it), but that counteracts the no registration needed, because every time u change ur address u lose a portion of the money still owed to u.
This is not correct. MaxPPS pays out the full debt the same way. The only difference is that you never get paid
more than you've done the work to get (like you do in proportional), while the pool keeps track of the operator's finances to make sure it doesn't pay you more than the operator has earned from running the pool for you. If the pool has to underpay you due to the finances, it also keeps track of how much it underpaid you so when/if the operator's finances improve, it can pay you extra. It is true that changing address resets this memory, and that is a real flaw to be considered.
