@arch idk, so lets have a look at the botsin.space blogpost.

> Server costs are "fairly cheap until recently"
i guess if one doesnt use masto, one can save even more money... maybe around 1/2 of the server costs of a well optimized masto instance, probably even more.

> Database storage (191GB growing)
DigitalOcean wants 50$ for 500GiB
Hetzner wants ~30$ for 500GiB

> File Storage and Bandwith (#1 cost of botsin.space, unspecified)
Lets say we use a combination with hetzner and a hoster with unlimited traffic as a cache:
~6$ for 1TB with 1TB traffic + a VPS somewhere ~5$

Idk but i guess that a "few thousend" bots on an instance used within a well choosen combination will cost around 50-100$ per month, and since it is a bot instance, one could easily decide that older posts can be purged so it would be way way less...

I wouldnt be terrified by the costs at all
