OK, I'll do your proofreading...

At the end of the robots.txt you are missing a colon from a rule that
disallows everything for all bots...

User-agent *
Disallow: /

That should be:

User-agent: *
Disallow: /

But if you just want to disable the bot you reckon is a problem, the
front page of their site (https://mj12bot.com/) says you want:

User-agent: MJ12bot
Disallow: / 

Or you could read their page to see the robots.txt syntax for slowing
down crawling, which I assume is relevant to other bots to you may have
problems with.

The other rules above your disallow everything (which are superfluous
if you keep that final rule) also have typos, you have a '0' here...

User-0agent: *
Disallow: /doc/

And this rule has a space in the URL...

User-agent: *
Disallow: stress test

I'm pretty sure URLs can't have actual space characters in them and
that must be a typo on your behalf. Also something I read when looking
at this issue a few hours ago (but can't find again) reckoned that
Google's bot let you have multiple statements on a line separated by
spaces, e.g.

Disallow: foo Disallow: bar

So it seems likely that having a space in the URL like you have isn't
legal, and could possibly upset parsing.
