Yes, you are doing a bad thing, thanks for admitting that you are in fact a botnet creator.
Botnets abuse the referral systems, making people who play fair, win a lot less satoshis. As such this is in direct conflict with the website terms of use, this what's and why it is bad.
Where coding a soft and spreading it, is not particularly evil, there harming regular players and website owners, definitely is.
Troubles with botnets can and are costing additional money, as the countermeasures against cheaters tend to be expensive.
By running this unfair net you are ruining, spoiling the fun for everyone else.
I know that almost nothing will convince you to stop, easy money have this corrupting effect on people, however think about symbiosis and equilibrium with the environment. If you drain the faucet faster than it can replenish it self than your source of easy income will be gone forever. Stop acting like a virus and than you will be entitled to objections about being condemned etc.
