First of all, don't panic. I have received this email countless of times and aside from checking the logs/files to ensure that there isn't any hack (I have a bunch of notifications which inform me about changes but I still just check to make sure) there's nothing else you can really do. If there is a hack then there are a lot of things you should do but, as you highlight that its not then we can skip this part.
You have not been removed from the Google index, you can check if you are still in it by typing "site:snipt.net" likewise you are still also #1 for "snipt".
As a result you should not submit a reconsideration request in fact, if you are ever deindexed I believe its the last thing you should do to get your site back in Google.
However, you may have lost some serp rankings for other keywords (I haven't bothered to check them to see if they have moved) although, they generally restore themselves once the GoogleBot revisits your site - which is a lot more than any other search bot out there at the moment - if someone is going to beat Google they want them to work a lot harder and smarter than them ;)
P.S. You should add a robots.txt file and sitemap.xml files to your site (the sitemap may exist but I couldn't see it)
Also you should .htaccess your site so the dynamic pages appear as natural pages - by this I mean change ?page=199 to /page-1 or /1 or even /page/1 (but don't use file extensions as its just an extra hassle if you decide to change your codebase later on).
