Gastrobeats - The People's Raffle : 2 winners with multiple prizes. A KOH-incidence?

GastroBeats, a month long festival had concluded on 22 June. 

Other than a month long celebration food, music and festivities, there is also The People's Raffle. Entry is by spending $3 on a bottle of Coca-Cola at the People's Raffle Booth next to GastroBeats and you can stand to win luxury resort and hotel stays, Air Asia Flights, Concert Tickets and even a BYD Atto 3.

While this sounded good, when the results were released, it raised more than just a few eyebrows.

Of the 30 prizes, 12 were shared between Tedmond Koh and Tedric Koh(Names found on Instagram posts by Gastrobeat).

While the odds of multiple win could be explained by bulk entries, the odds of having 2 winners dominating the prizes are much lower than one getting the first prize at Singapore Sweep.

While it is not explicitly stated that the 2 are related. Given the names, this probability is higher than having a raffle with 2 winners having multiple wins in the same raffle.

Nonetheless, winning multiple prizes in the raffle is allowed as long as they are separate prizes. Looking at the winner list, it technically warrents multiple prizes per winner. 

Coincidentally, there was a reply by one of the alleged winners on the Instagram post by Gastrobeats. The post mentioned that the duo had bought 1/3 of the tickets and thus expected to win 1/3 of the prizes. While it may sound logical, it begs the question - How would they know that they bought 1/3 of the tickets, given that the raffle tickets are issued via the purchase of Coca Cola bottles. Was there public information on how many tickets are available for purchase?

If not, would this knowledge of the number of tickets give a participant an edge in the odds for winning?

Futhermore, there were allegations that some of the winners are directly related to the event as vendors as per this reddit post. The terms of The People's Raffle did indicated that 'any agents, distributors and other organisations commercially connected to the promoter ' are excluded. If this is true, the results could be invalid.

For the record, the value of the prizes won is at around $11,300. While the value may not be significant, the KOH-incidence does leave a bad taste in the mouth for Gastrobeats that is well known for its food festival.
