tip: lex m/m (mature OR explicit)
Hm. That's interesting and helpful, thanks. It actually makes me wonder now, though, if the kudos will drop even more than expected, because while I have not exploited the multi-click kudos bug, I *have* left multiple kudos as a guest (before I had an AO3) account, then as my logged-in account on re-reading particular fics years later. I've also heard that it was possible to leave multiple kudos if you did so with enough time in between them. I suppose there's no use worrying about it, though, since it's something they have to go ahead with to ensure future kudos will continue working.
