Min/Max File Size
 

I suggest that in all searches ought to be a max and a min file size filter. Because when the user knows that what he wants to download is a file eg over 50000KB then the results should be filtered by this and this way many ads-viruses wont be displayed.
thx

That may help in the short-term, but not in the long-run. Once such a filter is introduced spam will simply increase in size. At least at the moment we know such junk files are less than 1,000 KB (1 MB). You can filter it out with your junk filter. That's its purpose.

yes but this can also used for searches to find what you need easier , not only for spam reasons
