During the competition in the "Roobet.com | Guess Total Wagers" thread ^Archive, I noticed that some participants edited their answers synchronously, every time when a new answers appeared in the topic. Then I checked the registration dates of all accounts in the thread and found that several profiles were created on the same month. Moreover, the registration dates of several profiles differ by only a few minutes.

Registration dates (this profiles list is far from complete, most likely):
February 02, 2017, 02:35:16 PM - peter0425
February 09, 2017, 01:34:03 PM - TravelMug
February 09, 2017, 10:25:39 PM - MiteLit
February 09, 2017, 10:27:53 PM - ornabldo
February 09, 2017, 10:30:41 PM - BattalgiaTR
February 09, 2017, 10:38:48 PM - s0nicwall
February 28, 2017, 03:11:32 PM - franklin9
February 28, 2017, 03:29:18 PM - USSENT
February 28, 2017, 03:43:39 PM - OVOBTC

It must be said that registration date alone is an insufficient argument to accuse someone of cheating, but this factor can be served as a motive for deeper investigation and finding other connections.

TravelMug & peter0425

From the records about the winners of the last 20 "Roobet.com Guess Total Wagers" contests, it is known that TravelMug has won five contests and peter0425 has won two.

When I learning that TravelMug and peter0425 accounts were registered a week apart and they changed their passwords on the same day in June 2018, I decided to take a closer look at these profiles and it turned out that their owner(s) speaking Filipino ^[1][2].

Sometimes TravelMug and peter0425 were registering in signature campaigns, within a few minutes:
1. Digital Developers Fund (DDF) Signature and Avatar Campaign (Archive)
2. Enigma Catalyst - Build Your Crypto Hedge Fund | Signature campaign (Archive)
3. Social Signature & Avatar Campaign (Archive)

Thoughts about connections between TravelMug and peter0425 have been in the air for quite some time. In 2017 there was the investigation of campaign manager DarkStar_ about these accounts.

Can't be 100% sure that both of these accounts belong to the same owner, but much probably they may be coordinated together.

It is worth to note that five profiles from the list above, including TravelMug, were registered on the same day, on February 9, 2017. Other profiles from the list have also a lot of similarities.

In the Roobet's topic, I didn't see a rule that prohibits the use of alt accounts, but in my opinion this should be obvious, because if some profiles are controlled by one person, this gives him/her a huge advantage compared to other users and a lot of space for manipulation in contests. It would be interesting to know the opinions of other users, especially those who participated in these contests.
