Some hosting sites advertise "unlimited" storage, but the fine print generally excludes "abusive users" from this policy. For web hosting, they'd probably consider backups of non-website data to a service intended for basic web hosting to be abuse.
Unless they have a home lab (sounds like they don't) or fancy expensive contract with a large cloud provider (unlikely), this is asking for trouble. Nobody offers unconditional data storage for free, its always a loss leader for another service and abuse will eventually get you banned.
Part of the problem is a lot of math is taught as pure theory. Unless you're one of the few people who finds math theory interesting on its own, it's soul-crushingly boring to someone with ADHD and feels like you're being taught how to waterboard yourself. It didn't help that my math classes were invariably taught in the oldest building on campus which probably had a single functioning AC unit. Physical and mental torture.
I managed to struggle through it, but only because I found physics interesting and it forced me to learn the underlying math well enough that I could progress to the next level.

A couple of her comics have been posted here, but I think its important to link to the source as well 😀 I definitely found some of the metaphors helpful when trying to understand why some expectations and interactions frustrate me so much.
Yea, nothing prevents them from fetching the pre-edited content from their daily or weekly database backups. Media such as images and video might be harder to restore, but "soft" deletes on that type of storage are common, and editing a comment to remove an embed won't delete the embed source.
