yes, it means that you have created more than one username. You are only allowed a single username on the forum unless prior agreement with the mods, or you will get banned.

As it says, multiple accounts are not permitted on HotUKDeals. Considering we've already had a user called "tissir1" (amongst others) that we can attribute to your bad self I think it's fairly self-explanatory.

Sorry, commenting is no longer available on this feedback.
