Considering how they don't want legit players to even have them, this might simply be something they over-looked when making the Relics a bit more available.
I could almost see myself making one even, but I don't think I will be going for it.
That said, those who actually have the players (or other) behind them to support them in creating these, are likely to have more than one in use and could maybe even use some of them at the same time and so...

Dare I say, balance, is the likely reasoning. ^^;

And no, I am not saying every Relic/et cetera owner is a cheater, or a manipulating evil person, or other, so if you have one or more, please, take no offense from this as it is certainly not intended. :]
