The people achieving this this round got banned and deleted , 12-15 accounts.
It wasnt just the casual 'friends' approach.
It was some sort of exploit which wasnt reported ( which is stated in the game rules ). I heard its getting fixed.
The other problem is there seems to be a new 'exploit' being looked at by the very same ppl.
But damage is done , the ban came so late
Vacation shouldn't have any bonus after all
