I have a currently private birdhouse run bot. I'll probably make it public/accessible in some manner sometime in the future.
The only issue with these types of bots is it eats into the runtime. e.g. for birdhouse, the bot is idle/sitting at the logout screen for 98% of the time. But that 98% of the time is still counted as time used. e.g. if you run it overnight to get some birdhouse/tree runs in (though probably one of the safest forms of overnight/24/7 botting), that'll still be 8 hours deducted from your monthly usage.
