As far as I understand, it works, right ?
You said it yourself:
Yes, the vote system works on my front-end!
These URLs in the redirect component means that something or someone called that URL which doesn't exists.
As Xavier said, it could come from a search engine crawler. Because even if the vote system is unpublished, once the crawler finds the URL is will call it.
That URL exists in HikaShop in order to up or down comments. But it is incomplete. Normally, the javascript of the page will complete it before using it. So the only way I can see that these URLs are called is that a crawler found the URL and tried to call it (crawlers don't run the javascript).
