On the other hand... that's still weird. Why would he do that? So that it's accidentally discovered three years later? But the posts are obviously edited, so it's not proof of anything. It's almost like he was trying to scrub all application posts (it's not only those two posts, there are a few more, all edited) to remove some other address. Would be interesting to dig up some archives and find if it was really the address that was edited, and what the original address was.
May be to defame Parodium for some personal issue? Just saying but I don't think both accounts can be owned by a single person.
Unfortunately, there's no older archive of both threads where spiker777 has posted the address. Well, I'm a little bit surprised to see the Dao.Casino (one campaign where spiker777 applied) signature thread archived in 2020 while the thread was posted in 2017.
I think why would someone change their address with parodium's? It's likely to defame parodium or parodium stupid enough to use the same address of his by editing there.(I doubt this being the case)
