I would be grateful if other accounts are also thoroughly checked

Yes, definitely let's see, the way they do things suspicious with fellow Alt.

Just to prove their involvement with another bunch of Alts.

Let's start with the campaign: [BOUNTY ALADDIN] 🔴80 000 000 000 000 BLUESPARROW Pool / Escrow 🔴.
CAMPAIGN RULES MENTION:

• Registrations with multiple accounts are forbidden and lead to a permanent ban with no reward.

Let's just take the address used by: @Williamm07 and the transactions they do.

Main address @Williamm07.

BEP20 Address: 0x649646C1b9235C47495B0E3Da13635277F3c4716

Here we can see, @Williamm07 sent 0.054BNB to @HardCore12V from the token sale they got in the campaign.

Conclusion: the three of them in separate campaigns.

Just to prove transactions with other accounts, are they really linked Alts, it turns out they are a bunch of sneaky Alts.
