I am pretty annoyed by this as well, but after stopping to report every single character I suspected of botting earlier in the game's life, only to see the same character the next
day, the next day and every day after that it started to become clear to me that SE just doesn't give a flying crap about ToS violations. I stopped wasting my time reporting cheaters and
bots forever ago.

You could do as I have done and stopped caring as SE obviously does not care themselves, and just enjoy the game or you could just quit for another game if it bothers you that much.
Pretty terrible that it comes to that, but it is what it is. Maybe a few years down the road after RMT have destroyed every aspect of FFXIV's economy, SE will do something about the problem.
History is repeating itself.
