Haha, my "workarounds" consisted of being persistent with a few different support emails I found, posting on the Chromium support forums, and a few other things. Pretty boring stuff, and I'm not really sure that it even worked.
Weeks or months from now, I'm sure someone will get their extension removed from the store, and may come across this post scrambling for a solution. If that's you, please reach out to me and I can send you the support emails and everything I tried.
