But however, is there any rule that says having multiple account prohibited in this forum?
This isn't a question about the right to have multiple accounts or not. Owning alt accounts isn't against any forum rules.
This case is about a person who had one of their forum accounts banned. A ban doesn't apply to just one account, it applies to the person operating it. That means if one of your accounts gets banned, then all of them are banned because you (the person using the accounts) are banned.
I think I keeps learning everyday, never knew about this section of the rules but I am grate is from a reputable member telling me this and again I have added this to my dictionary for future use.
But from what op is saying, there seems to be a big different between the both account as the already ban account was a business account while other was a personal account does this also applicable to both account?
Sorry to ask much because I really want to get a clarification since I don't know everything in the forum.
