I'm agreeing with you here, and this is what tipped me over the edge.

First Registration
Bitcoin 23.0
Quote420
MD_ASIF

all entered the same two Sportsbet.io contests in quick succession of each other:

First the most obvious instance of ban evasion, MD_ASIF:



1more is banned thus MD_ASIF is ban evading.

Also used by IDEA2.0 and asif0990, who are also banned, so it wasn't a one-off mistake:

It has already been established that Nitu007 is First Registration. Instead of sending BNB from one account to the next to pay for token transactions, they have been using a series of hop addresses in an attempt to make the connection less obvious. For example:

Nitu007 / First Registration to
0x355d5b474e10d278fa0607b27e567d2d2878c1ad to
0x3ffd1950bb7528f1df5b67e419553a8302d96abd to
0x9bdcffef5ac65b02d43393b70e62c734c3835054 to
0xe6e09b38f994c38a0c8e0a27cb72f8fa17d43982 to
0x107305e771c62028c27856c05c1080ff5adf41a2 (Bitcoin 23.0)

All the middle ("hop") addresses have 2 transactions in them for tiny amounts of BNB, a receive and a send.

Now for Quote420:




They edited their post a week later after noticing their mistake.

I'm also wary of this BountyProgram account as they seem to show up wherever the others show up, but leaving them out for now as they have not yet actually entered a bounty.
