Instead of just reply and point out the obvius thing in every topic you find. How about spend a second to READ what people are writing?
I perfecty already know it is not against any rules to have multi account. For that reason I began write " I would like a rule..."

I send DIFFRENT boosters everyday to everyone I have as friend and still dont get any back.

19 of 20 matches I play I have 0% possession bonus from friends, I would be happy to have those 15% too. If developers wanted everyone to get everything easy and get maximum bonus, why have it. Why not have everyone get one of each booster when log in and every match both players get 15%. no need to cheat for anyone, save the trouble for everyone to create tons of accounts each.
