А вот и результат:)

Несколько фрагментов из переписки с администрацией относительно футболки за August Cook-off 2014 и судьбы предыдущих призов, публикую здесь с разрешения отправителя:)

We do send goodies to all our winners, however, in certain countries due to custom rules it remains hanging with the custom department. So if you and your friends have not received certain goodies of yours it could be because of the same reason. So we would request you that if you could connect us with some of your local vendors who can print our t-shirts and get them delivered locally it will be great. Also if you have any other suggestions regarding goodies feel free to let us know. We will be happy to do our best to get your winnings to you as soon as possible.

Also, kindly let us know the details of you and your friends from Russia and Ukrain who have not received their goodies. We will look into the matters and makes sure that you guys get your goodies in coming days.

We regret the inconvenience.

Yes it will be great if you can post the answer there. We too use FedEx, DTDC, and the Post Office services for delivering our goodies. It's really disheartening to know that so many of winners have not received their goodies. We have started digging into our records to find out the status of all the goodies that have not been delivered till now. We will soon try and get in touch with any user who has not received his/her goodies. Also, if you know users who have not received their goodies, kindly redirect them to us.

Так что если кому-то не пришли одна/две/пять/десять ихних футболок — можете связаться с ними и сообщить об этом; судя по нашему диалогу, им не было известно о том, что уже довольно длительное время многим пользователям их призы получить не удавалось.

С их форума — "There are T-shirts in Long contest for : Top 10 global . Top 20 Indian . There are 10 T-shirts for top 10 global in cook-off." А также топ 10 для оптимизационной задачи, я именно за это получил.
