From "Google submission hammers section 92A", by Ted Gibbons, for New Zealand PCWorld:
Google notes that more than half (57%) of the takedown notices it has received under the US Digital Millennium Copyright Act 1998, were sent by business targeting competitors and over one third (37%) of notices were not valid copyright claims.You see what's wrong with that, right? The 57% doesn't bother me so much, but only if the claims are valid. The 37% is horrible. I could go on to explain why, but I'll let the EFF explain the DMCA.
