Day (0) bitcointradesg registers, Day (+1) cryptoxchg registers Day (+2) bitcointradesg creates their Singapore BTC thread ( archive ) Day (+3a) cryptoxchgg registers and four minutes later starts a thread selling BTC in Singapore Day (+3b) sugarwomen registers.

24 hours after bitcointradesg starts their thread skorms posts this (two and a half hours after cryptoxchgg starts their thread on day +3):

bitcointradesg naturally denys the allegation:

Hi, I am not affiliated with that person.
Obviously that person has no sense on what the repercussions are with copy and pasting someone else's post, and creating a username almost similar to that person, posting it on the same forum and outright. What effect that has on the trust strangers would have to place in another online anonymous user met through a forum. This trust issue is of utmost importance especially when dealing with 5-6 digits. You should be in fact worried to trade with someone who places little emphasis on EQ or trust.

I'm officially stating that I'm not associated with that person.

In terms of proof, feel free to look at my posting history to see that I have been active ever since I created my account. We are also on different telegram accounts, apparently.

I am currently finalizing a trade and will request for the person to post a review after we have completed transaction. I will also provide some proof of the completed transaction after

So, let's start by looking at cryptoxchgg's two posts:

hello guys.
i have a fair bit of bitcoin/ether to sell in Singapore.

buyethereum21@gmail.com

thanks:)

I can supply ~100k sgd worth of bitcoins or ethereum at live market rate daily. This supply would increase next month.
Prefer otc meet up if we're in the same country. Otherwise we can use online impartial escrow services, like localbitcoins, as I'm new to the forum and we don't personally know each other, so yeah we should protect each other.
I'm selling at market floating rate +6%, at which timing or market rice to your convenience.
Looking for frequent buyer!
Kindly add me on telegram @chuckles00 to discuss further!

cryptoxchg posts just once (prior to bitcointradesg starting their thread mind you) in a thread called "Singapore" Archive

Crucially, cryptoxchg posts at January 22, 2018, 05:52:40 PM GMT and it is not until bitcointradesg's first post at January 23, 2018, 07:09:09 AM GMT that we learn bitcointradesg is in Singapore.

buying/selling btc

Hi, I am able to supply around ~100k USD worth of BTC daily. I am a direct seller. I see your payment options and the best one I have access to is china bank. Can I you add me on telegram @Shabbs to discuss further? Cheers!

Conclusion:

cryptoxchgg was not created to be a copy cat as the original "single G" UID was created *before* the thread began. I feel cryptoxchg was created to start threads in other sections of the forum as for some reason cryptoxchg - the "single G" UID couldn't be accessed (locked out??). After exposure sugarwomen was then created to bump the thread having just four unremarkable posts in a six day period then likely gave up on the account other than to look back in in May 2018.

Case #2 2 Accounts Connected:

In the locked thread Limburger wil BTC verkopen: Waar? https://bitcointalk.org/index.php?topic=2028957.0 ( Archive ) the second to last post by Btc2Boy uses the same Telegram contact details
