For me at least, it's not that you're asking questions. I answered, so obviously I'm sympathetic to confusion in this area. I'm just trying to encourage you to seek your answers in the documentation and manuals FIRST. The way your question was worded led me to believe that you had not read the manuals at all and were simply copying snippets of code and commands from some random question and answer style forum that did not teach you anything about the fundamentals of what those commands and code actually did. That's fine too, lots of people started off that way, myself included. Reading the manuals gives you the context to step back and understand how those commands work and what they're really doing. If you do, you'll be much better able to troubleshoot your own problems, you'll be able to ask better questions in forums like this, and you'll get better and more useful responses.

With all due respect, RTFM. Mount and umount are two sides of the same operational coin. You mount the drive to use it and unmount it when you're done. fstab is just a file system table used to remember and consistently apply the options used whether you're mounting the drives manually or telling the system to do it at boot.
Deleting a line from fstab is not the same as unmounting, it is just a shortcut to tell the system how you want that drive mounted when you or the system run the mount command. Mount directories (usually the folders in /media/ or /mnt/ ) also do not get automatically deleted just because you "yanked the drive". Again, those directories are just where your system is expecting to mount the drive. When the drive is mounted they will be the root path to its contents, when the drive is unmounted they will be empty but they still exist. If your planning on mounting the drive again leave them there. If you're not planning on mounting them again, delete them.
If you're not planning on regularly mounting a particular drive, it probably shouldn't be listed in fstab and you should just run the mount command with the appropriate options (again fstab is just a table for remembering those options for the mount command).
Many desktop Linux distros are also capable of automatically mounting new removable drives in such a way that the user can access them and doesn't have to worry about touching fstab or the mount directories.
Just in time for Google to kill RCS and move on to something else.
Armchair pseudo-scientific thinking like this was why Mythbusters became so popular. They even devoted at least one episode to this very myth. Spoiler, hydrogen wasn't what made that particular lead ballon unsafe.
Blocklists are ineffective by design. Each and every member of the swarm can collect all the data necessary to flag you to your ISP. Obviously any professional collecting this kind of data can avoid a blocklist. There is no such thing as a better blocklist.
Teach us then 😭
I think this hits on another big generational difference. Those who grew up in the early days of personal computing and the Internet didn't have teachers or a hallucinating language model to spoon feed them instant answers. They had to actually RTFM thoroughly before they could even think of asking in some arcane BBS, forum, or IRC for help from elders that had absolutely zero tolerance for incompetence or ignorance. MAN pages and help files came bundled, but the Internet (if you had it) was metered and inconvenient on a scale more like going to the library than ordering a pizza. They had to figure out how to ask the right questions. They had to figure out how to find their own answers. The Internet was so slow that all the really interesting bits were often just text. So much indexed and categorized one might need to learn a little more just to find the right details in that sea of text. There was a lot less instant gratification and no one expected to be able to solve their problems just by asking for help.
I've seen way too many kids give up at the first pebble in their path because they are so accustomed to the instant gratification that has pervaded our culture since the dawn of smart phones.
A decade ago we figured out blacklists were ineffective. What's changed?
I bet you go to Taco Bell for Cinco de mayo too.
Hot take: to Most windows users (not you) probably shouldn't be able to access power shell or cmd.exe at all.
Start with the man pages. Running the command man followed by a space and then followed by the command you're using will almost always give you a man page of the basics of how that command works. The fstab has its own man page too. An internet search "man fstab" or whatever command you're interested in should also net many mirrors of the those man pages as well.
