I have no relation with user Lekhac37. Why am I mentioned here? I think he copied my proof of registration format and submitted it.
Is this some kind of joke? Did he jump in a time machine into the future, copy your address, and then go back in time and post his post? Look at the dates of the posts. Lekhac37's post is from 2021 and your post is from 2022

So who copied the address from whom?

You need to look at the campaign name. 0x8E456599dB2429cFf0AC8f9d5b5aA29E7C921642 - This is my address.

It says Bitchemical.
What does this says?
