I confirm that in the terms and condition they discourage the use as a private cloud backup and only to host stuff related to the website. Now… until now I’ve had no complaints as I’ve been paying and kept the traffic at minimum. I guess I’ll have to switch to some more cloud oriented version if I keep expanding. But it’s worked for now !
There will always be new and smaller instances tho. Like it was true for smaller communities in reddit. It’s all good and well until they get exceedingly popular and a shitshow.
