Best I can offer you is removal button and display of the vote on the group page itself. Because the rating system is part of the IP.C which is obviously something made by IP and not me. But the records, and all that backend stuff will still be there.
Thanks! I think display of the vote (or # of votes) on the group page itself could be helpful from a reader's perspective. Page layout wise, currently the follow count is just above the rating stars. Might be some trouble to find space for another number or an Amazon-style horizontal bar chart, if that's what's pre-built from IP. If reps. of the scanlation groups would also find this feedback helpful, then it might be worth adding to the to do list.
Thanks for all the amazing work you do to make this place so welcoming.
