Pretty simple, the thread was created just for a troll. What does make difference if a user becomes inactive for a month or two if there is no something suspicious at all? As I told you before, this forum isn't everything in life. There is a real-life out of this forum and anything would happen that we are unaware of.  It doesn't mean anything. Most likely OP has some issues with Yoshie and that's why he has created this thread. Yoshie didn't reply on this thread because he believes that is just a troll and he shouldn't respond to the troll. He will start scam/spam busting when he fully recovered.

Locking thread would be better to avoid more troll.
