On sites where DMCA bots spider, you can always give a bogus URL.


for example:

say the link to your file is:
http://hotfile.com/dl/39862007/myfile.rar.html

You simply post it as:

http://hotfile.com/dl/3986200X/myfile.rar.html

and tell the users to replace the "X" a "7"

This slows the bot down until a human DMCA person grabs the correct link.
