kbin.run meta

There has been a long standing issue of guests and/or bots subscribing kbin.run to an exorbitant number of seemly random magazines with either no content or super strange topics. As the site admin, I was getting automatically subscribed to each and every one... this issue has since been mitigated by a recent /kbin update that now requires all site visitors to be logged in if they want to follow any magazines that are not already subscribed to by an existing kbin.run user. For those curious, I removed a total of 404 (lol) dead or stale magazines with zero subscribers.

Hopefully this will further improve the site's performance by stopping any unnecessary junk from getting stored in the database and/or R2 media bucket.

EDIT: if you're looking for a particular magazine that you know exists but cannot find it in the search, let me know as I may have to "untrash" it... it's possible that it could be one I removed.
