Valid high severity. There are two impacts here due to the wrong setting of the `refferalInfoMap` mapping. 1. Wrong refferal info is always set, so the refferal will always be delegated to the refferer address instead of the caller 2. Anybody can arbitrarily change the referrer and referrer rate of any user, resulting in gaming of the refferal system I prefer #1500 description the most, be cause it seems to be the only issue although without a poc to fully describe all of the possible impacts
