I recently got a tax rebate (not a refund, my state is distributing part of its budget surplus to taxpayers) and decided to make a donation to Planned Parenthood. I have parental controls set to block adult content. I could not access the PP site (tried 2 different browsers). As soon as I disabled parental controls, I was able to access the site. I assume there must be some language on the site that caused this as I don't expect there were any X-rated pictures! I think this happened once before but I can't remember what site was blocked.
