Who would pay for someone to host their blockland server in the first place. Costs less to just leave your computer on.
• Bad CPU or low RAM
• Unreliable network or electricity
• Computer is not suited for 24/7 use (laptop or all-in-one PC)
• Insufficient upload speed
• Located in the middle of nowhere, which provides bad ping to 95% of players
• ISP's terms-of-service ban running public servers at home AND the ISP also cares about it
• Need to worry about keeping the BL server up-and-running
