I'm going to serious reply to this because FUCK IT.

Let's make a betbot.

Open a betting server, put betbot as owner. Periodically change mods to keep things interesting (for the players to stick around.).

The bot will monitor players stats and bet on matches it's pretty sure it will win. The goal would be to win ~60% or so of bets to keep it self-sustaining.

If it made a good enough profit, global on modchange to get people into the server.

It'd be simple, but making it win often enough to matter would be the hard part.
