I am creating bot in Discord.js and I would like to reward users for bumping/upvoting our server. I know there are bots that can track bumps on disboard.org (eg. bump reminder).

But what about discordbotlist.com/servers? If some user upvotes our server, is there any way how to find out the user identity? I checked their API, but there is only event for upvoting bot, not server.
