I think a solid compromise would be to disable the sticker notifications by default but allow users to enable it in their account settings. I get that there are some people who care way too much, but it really was a good way to determine if a thread had recent activity. If there were high likes or dislikes it could indicate if there would be people building upon those idea or proposing counterpoint. Changing the defaults would filter out alot of mouth breathers complaining about their reactions, and I really did find the notifications to improve the usability of the site.
