There’s always a possibility of someone posting arbitrary content when a platform allows user content or combines content from many sources. I mean we do have moderation here and illegal content is supposed to be removed or flagged. However as the operator of some internet service, you are ultimately responsible for what’s on your instance. So you definitely do need to make an effort to stay in control. Btw, there are possible compromises, such as using an allow-list of instances you federate with, so you don’t pull content from sources you don’t trust and didn’t approve.
Btw, the proper place to mount filesystems is either
/mediaor/mnt. I wouldn’t create a directory called/Volumesin Linux. And pay attention, these are case-sensitive and most (not all) system directories have agreed on using lower-case letters only. And “volume” is kind of a Windows and MacOS-term anyway, I rarely see Linux-people refer to media and filesystems that way.
