Your seed was someway hacked, some investor was losing a lot because of this ( and it is your fault just to state clearly how I see it) and tried to limit their losses.
Basically now they are the only one who suffered a loss because you have that great security measure for which you manually process every withdrawal.
From an external point of view it's kind of ridicolous... but if I was an investor I would be very disappointed.
It could be seen also as an inside job to keep some of investors money... but Am just putting it here as a provocation and not something I really think.
