You are absolutely right. It has always occurred to me that women and men who are seeking help are often found out via the history search. Some abuse sites have an untraceable "escape" bar, JUST in the event that they are being monitored by their abusers. I had never known how to erase the history OR check the history, so I couldn't very well suggest that people cover their tracks.
What a timely post, BeenThere. I think your post should get a BSA or an RN, at the very least.
