thank youuu

Hi,
i write you because a sgtools message.
Today i wanted to join into a birthday train ( https://www.steamgifts.com/discussion/s5QrV/sgtools-4-years ---> http://www.sgtools.info/giveaways/4f9aaa76-fd0f-11e7-907d-fa163ee2f826 ) and seen a message at the top ( You are currently serving an infraction until
2018-02-18 23:32:26 NY Time ).
I am complete confused because i am 100% sure that i activated all games. Not double win anything.
At steamgifts i have no message over anything.
I synchronized steamgifts AND sgtools. Both bring nothing.
I can't explain it to me.
So i question you.
What is the problem ? What bad should i had done ? o_O

friendly regards
Masafor
