One of the bots I encountered was able to turn a public tournament into a private one (which made it inaccessible and hidden from the multiplayer list). The user using the bot was able to earn 500 TC per ~50 seconds. With the bot set to automatic (requires no manual labor from host), it's basically a scenario where the bot is gaining millions of TC in a matter of hours.
Clearly, it's a lot more than multiclienting and force-pinging. Don't whine about this when you aren't aware of the specifics to their full extent.
