A necro post in a gambling discussion? I thought this would be a copy-paste and sure enough Google agreed.
There was a post by
jt byte in the same thread.
The original post is there in Google Cache and has been deleted.
My hypothesis - apriloni is an alt of jt byte and is deleting posts in 1 profile and posting it in the other.

So does it mean that my
hypothesis of users deleting their old posts and submitting them again got finally confirmed?
Kind of. But this wasn't a newbie deleting old posts and another newbie posting them.
The original post was by a Hero member. I guess the account must have been banned if the user didn't mind deleting the posts.
Are banned users allowed to delete their posts?
I understand that it was a Hero member, but couldn't the same be done by lower ranks too, especially if they get banned (provided they can delete their posts, of course)? Also, if they have enough posts, their activity shouldn't go down as long as the number of posts matches (or exceeds) the required minimum for their rank. So there is at least one reason for doing that, right?
