another thread, but want to make sure it's also seen here.
Yesterday, we identified an item duping bug in ESO that some players chose to exploit. We acted quickly, and have since fixed the issue. We have a zero tolerance policy when it comes to abusing exploitable bugs, and those who were found doing so have has their game account permanently banned.
We want to thank everyone who reported this issue to us. In the future, should you identify what you think could be an exploitable bug, please send it to us in-game via /help or in our help center:
