Welcome to the Q&A Forum

Your sitemap will already be doing that and you can get Google to index a page almost immediately by using the "fetch as Google" section in your Google Webmaster Tools. Probably not a direct answer to your question but have you thought about putting all those helpful links on your 404 page instead? Your site instantly goes from Zero to Hero in my eyes if it has a friendly 404 page

I do get myassignmenthelp scam as a suggestion I am afraid.  There are quite a few similar suggestions coming up as well.  You can check them at ubersuggest.org "Is this work of a hacker..." Impossible to say for sure based on how much I've looked at it, but if those domains are legit then I would say that it probably is. It looks like a hacked wordpress plugin or something allowing them to create additional pages.  It's quite clever really. If there is a referring URL it  doesn't redirect. So, if you follow the link from a search result (or anywhere else) it redirects, but you can view the page if you do directly - or if you are a web crawler. "Most Imp how do I counter this without  starting a spam-war???" Tricky.  I'd start by setting up alerts to find any new occurrences.  I'd be looking to try and contact the owners of every website this vulnerability is being used on.  I don't think that Google has a means of reporting redirects, only malware.
