I'm curious why this question was deleted? Sure, it's a little weird, but I'm guessing there's an easy answer to it. (And the OP has asked it again, on main. Again.)
The OP doesn't have sufficient privilege to participate on meta. It is unfair to other users to allow this user to "skip the line". (Especially as it is clear that that user has little intention on properly using the site. They claim to have a "real" account, which should have sufficient privilege to participate here, and they are welcome to post their question on meta with that account.)
I have a registered account that I don't like its number because it reminds me a special date that I lost a good friend.
Literally one sentence later:
Unfortunately I noticed this fact too late when the number of my posts reached to a point that I can't ignore it to simply delete my account and open a new one with a different number.
Obvious troll is obvious.
To those who, thus far, disagree with my claim, I would like to indicate some further evidence. Anyone genuinely interested in trading accounts would be unlikely to add the reply of "User 1":
I will not make any deals with you. I've registered to this forum. My account will not be removed, relocated, exchanged or renumbered! My account is my own. Please leave me alone and don't ping me again.
which in itself already has a scent of artificiality over it (emphasis mine). Especially considering the reply of "User 2":
Your offer is really strange but I care about the humans' emotion much more than the numbers. If having an account with such a number is that important for you and makes you really happy, I have no problem with the exchange if the system administrators have no problem with it. You should ask them about it.
Everything is pointing too perfectly towards the meta question subsequently asked. Furthermore the writing style of the post and the two "User" replies is strikingly similar.
As a final point I'd like to indicate that the "offer" that was allegedly made is rather complex and therefore unlikely to yield answers so precisely aimed at what OP intended to ask.
