Yea, I think that Fencer should start trying (if possible) to limit the number of accounts that one person/household can make accounts with.

I mean they should not be a strict as IYT that bans accounts if 2 people use the same computer, but more probable could be done.

Then again, I don't think too many people who keep creating new accounts just to get "extra's" - I'm sure there would be a few, but I would think very few.
