page not found

Hi everybody, In the past few weeks I noticed someone is attacking my site through my in-site search. They search with Chinese characters. - the search result pages did not get indexed because they were tagged as no-index but they were using my crawl index. Changed many things to avoid this...

Hi, i just purchased a website for it's domain name, I installed anew WordPress theme and plan on starting it from scratch, however I deleted all previous content and now I have something like 600+ 404 errors in GWT, what should I do with those? How do I get rid of the 404 errors? many thanks
