Just an update. I haven't heard back from SnackTools directly, but the three Zam addons have been removed from the site. It would seem that the site on which the files are actually residing (SnackTools) takes the matter of copyright seriously and they deal with it quickly. Less than 24 hours, exactly as they said to me (quoted previously). So yeah, guys & gals, don't even bother fighting with the ESOcore guy, go directly to SnackTools.
As a reminder,
this is the page you need to fill out to ask SnackTools to remove your files. I've attached a screenshot with some sample text you can look at.
