My question:
• Who deleted the post, mod or himself.
• If it is a mod, why was it removed while some of the rules are clearly stated about the Alt account.
To me it's strange and suspicious something is going on.
I don't think forum moderators have deleted this post where there is specific rules about Alt accounts. Most probably it was deleted by "gunungkembar" and only he can give proper answer about it.
Have you contacted him to know actually what happened?
• if @gunungkembar itself deletes why and what happens after he publishes it here.
To know more details about this we have to wait for him until he feel it necessary to make a response here. Looking forward to see his description about this.
