This is something that has crossed my mind many times since i registered here. I can't find anything in the rules about using more than one account at a time. I don't know, maybe i'm missing it or there simply is no rule against this.
But regardless of whether it's in the rules or not, i've noticed that people have been banned for using a dupe account to pretend he's someone he's not (for example a trader registers another account where he acts like an "anti-trader"). When people are catched for things like this, either the dupe accounts or all of them usually gets banned.
So again, maybe it's just me being a sloppy reader, or this question has some merit. When is it ok to use more than one account at a time, and when is it not. Because frankly to me it seems like when it benefits FST (read: when someone uses a dupe account to leak tracker information such as reviews) it is all good, otherwise it's not. Please correct me if i'm wrong cause if that's the case, it seems very hypocritical to me.
