There's a couple communities that I have blocked perky because they're importing posts from reddit. Not screenshots, but years to decades old posts that are archived. All the power to you to waste your server space, but do it quietly.

In that case leave the files alone for where they're located.

You could install sudo instead of jumping into a root shell every time you need to do root privileged tasks.

For the first question, are you using a package manager? If so, I'd say leave it alone. For the second question, your root will likely still be bash unless you changed it yourself.
