FTP error log question

[pityocamptes]

I was checking my error log and I seem to get this, but everything is working correctly, should I ignore it?

[Tue Jan 27 19:46:49 2015] [error] [client XXXXXXXXX] File does not exist: /var/chroot/home/XXXXXXXXX/html/general-discussion
[Tue Jan 27 19:46:49 2015] [error] [client XXXXXXXXXXX] File does not exist: /var/chroot/home/XXXXXXXXXX/html/missing.html

Replace the missing files

Probably just a bot? Just a basic 404 error.

2 possibilities:
1 ) People are linking to a non existent page on your website
2 ) People are guessing a url / page that doesn't exist on your site and trying to access it.

99% of the time, it's option #1
