Your corruption of reputation gain via using multiple accounts to like all of this account's content is not going unnoticed, friend. All of the other accounts you are using have little activity too, increasing the likeliness of this corruption being true as me and others well think it is.
What can we do about it the mods won't punish you for it you will just have to deal with alot of the forums having an active dislike for your method of getting your rep up. Pretty much as you are getting more popular with your rep you are infact getting less popular with the forums.
