And archive-locking will make your fic not show up in searches by logged-out users, so that's less than ideal.

I'm a little surprised the bot is still running -- haven't heard anything from it in months, if not over a year -- but knowing you got hit by 20 kudos, the bot is for sure where my mind goes.

To further confirm it's the bot, check the hits. An increase of 20 kudos should come with at least 200 new hits (10% being high end of normal for a kudos to hits ratio). The bot doesn't give any hits whatsoever, and can even result in a number of kudos greater than the total number of hits on the fic, as it did for some of mine.

Hope this was helpful.
