Points

I had 360 :O

Because you had the max number of points (300) and then a giveaway you entered was canceled and those points returned to you which put you up over the top. Its only temporary so spend them while you got them.

when a giveaway is deleted, the points are refunded.
if you have 300 in the moment of the refund, then you have over 300.

You enter some giveaways.
Before the end of said giveaways you reach 300 again.
Said giveaways get canceled: you get your points back, even past the 300 points limit.

Is it possible that some giveaways you entered got deleted and you got the refund? :D
