Quick Question - Why need to block crawlers, search?

[zzzzk]

Hello, quick question.  You have the option to block crawlers, search engines. You also have the option to use a recaptcha.  I can see the need for this in user registration or forms.  (spammers or false accounts).   However, why would this be needed for jdownloads for files such as music or docs?  Do crawlers, search engines actually download the files? Is it needed for security?  Thank you

Hi
There maybe many reasons why you want to block crawlers from indexing your Downloads. The three principle reasons are privacy, security, and excessive traffic.
Most people do not block the crawlers but there are some 'bad' ones.
