None of that is true - in fact - if someone attempts to remove your site - without following the law - THEY ARE LIABLE FOR DAMAGES:
http://lcweb.loc.gov/copyright/legislation/dmca.pdf
That is a summary of the law - read around 12 - 14.
Basically, to shut down your site - they must certify in WRITING under the penalties of perjury - that your site is infringing to your upstream provider. If they lie - or make a mistake - they are liable for your lost income.
You must be notified - and then you have certain rights - if you own a TGP - you are supposed to do the same thing - the copyright owner certifies in writing that one of your links leads to a copywrited site. You take it down and tell the person that submitted it so they have a chance to respond and defend themselves. The TGP is protected - as long as it receives the required notification. You are 100% protected if you do business this way. You DO NOT NEED ANY PROOF UP FRONT to protect yourself.
I would be happy to write up a summary of the law and exactly what must be done by link owners and the like, but nobody seems to read my posts anyway

If people want it - I will do it.
The laws on this are 100% clear.
