@Trel:
No. Separate downloads of individual addons does not qualify as a collective work or compilation. Compilations are single packages containing many addons that are intended to be used together, eg. ElvUI or JoeBob's Awesome UI.
However, based on the text you quoted, I've determined that Curse is displaying an old version of my license text, and their edit function is not currently working (which is probably why it's displaying an old verson), so thanks for the heads-up. The actual license as included with the addons was updated quite some time ago to clarify what "compilation" means in relation to WoW addons.
(Edit: Okay, I guess it's only partly broken, and just ignores the form submission 2/3 times. It's been updated now.)
@ronburgundy:
Thank you. However, it shouldn't be necessary for me to constantly monitor your site to make sure you're not re-uploading my addons. If you're going to insist on using automated scraping to copy addons from Curse, it should be looking at the license, with a whitelist that only includes licenses you guys have actually checked for compliance, not a blacklist or whatever other method it's currently using. :(
