It looks like Decent logged in today and have deleted the original post - https://bitcointalksearch.org/topic/--1162392
Scam officially confirmed
Well, it could also be an account hack and the opening post was not deleted by the actual owner. It doesn't really make sense to just remove the opening post if it's a scam, then it's enough for the owner to simply disappear, also because the post and full thread is still and will be still available at archive.org and Google Cache.
could you give us an abstract of what is important on archive.org, or a google cache link?
seems that a thread with 800+ pages cannot die like that..
