All three accounts mentioned by OP have different problems but it would appear OP just made everything up in an attempt to frame these three users. For what reason I don't exactly know.
Of course anyone could pretend to be topman21 on Telegram, or any other user. There's no proof that this is who OP was talking to, if he was even talking to anyone besides himself.
The whole stuff sounds like a framed-up story for retaliation.Anyone can claim to be someone they are not on telegram just to make sure they get at someone who once got them hurting years back.
According to LDL, this is what he thinks led to the frame-up.
Why have I been framed?
I will tell you the whole story of this plot, so you can easily understand how I was framed here.
The incident happened a long time ago when a manager named "Kakatua" was running a forum project with his multi account group. Then a famous user of my Bengali community "invincible49" introduced the Kakatua group as a multi group. And their accounts are given negative trust for the offense of multiple accounts.
Since then, the "Kakatua" group has developed a grudge against invincible49, and the revenge of that grudge is the current event.
The Kakatua group didn't stop after getting feedback from 34 other accounts including kakatua. From then on began the "SmallRabbit" management fraud. Their journey could not go far. Invincible stops them from cheating and destroys the entire group by putting them under a penalty.
Since then he distanced himself from Bounty Manager and started his journey with a bought account "Smartaction" and he started working on a reputable campaign. But even from there invincible49 caught him and managed to get the account back to its original owner.
In each case invincible49 then plays a role in delivering the cheating cycle.
Now the bottom line is that the cheating cycle has been repeatedly damaged by invincible49 but in no case they have been able to retaliate. As a result, the fraud circle later compared invincible49 to me and started thinking that I (LDL) was personally invincible49 (Now inactive) and they took a kind of invisible revenge on me with their created group (nitscam420/Xavi20/Topman21....). Forcing report and sending a planned $40 bitcoin (to my LDL address) connected to (Topman21) report which was all their planned plot or animosity.
Unfortunately, LDL was on their list to get back at. I can't say whether the story LDL tells is the truth or not but whichever way, this sounds like a framed story to me just to get back at LDL
