Is the problem related to the trading bots? Those can be anyone's. As long as the exchange exposes an API for them, any user can have them. And with sites like Binance, I expect that you won't find the owners of them. Good luck with the lawsuit.
I don't see where's the harassment. One can buy or sell at market price or put an order and wait patiently to see it filled. Ah, the trading bots will always try to put a better price than yours? So what?
