Yes... take a note from the game wherein the RMT managed to create spam that could effectively make it so you couldn't under normal circumstances, block the character because they made their message so large it literally made it so you couldn't see who was doing the spam .
No offense intended, but ESO is far from perfect, though I do sort of like the account-wide idea, it is rather clear that going for accounts doesn't matter - they are often using stolen credit cards and accounts, as was evident in the pre-release.
While this didn't impact my decision to cancel my pre-order for the game, what made me decide to cancel my pre-order was the sub-par gameplay.
