Oh, I know. I guess we're supposed to be thankful for being able to submit a single file, though.
I also noticed that the help page states "(the file type must be .txt and it must be encoded in UTF-8 or 7-bit ASCII)". How many non-technical people even know what that means?
How many websites that are concerned with SEO cannot find somebody who can know what that means for them?
And what are the chances that if somebody doesn't know what that means they will mess it up? It is not like UTF-8/ASCII is something that you have to go out of your way to choose.. it is going to be what is defaulted to.
Whether or not they have heard the term before, I think that people who care about their website's google results and don't know how they could possibly find someone to help them make a text file are a minority not really worth worrying about.
"- Edit the file so it contains just the undesirable links."
That's the part where intensive manual labor comes in, weeding through those links one by one.
