again thank you for the report!
we removed from our base for about 120K links to load.to, mediafire.com and freakshare.com.
also say that many of these files have already been deleted on hostings.
so, we have removed about 155K 2shared-links & 440K shareflare-links from our database (pseudo-pdf files). it's real huge amount of fakes! will check on and watch out for new suspicious submits.
please, report us about such cases in the future! thanks for you : )
