Traditional submission software are unsafe. They continue to use old templates even if sites change. They guess proper categories on sites. They ignore warnings on submitting incorrect data. This may result in putting your product and company names, your domain names, IP addresses and other info into blacklists on download sites. You will submit your products again and again but they will never appear on these sites. And you will never know why your submissions go directly to the trash.
This is why we make different posting forms for different categories. We do not hundreds of websites we have only the sites that matters.
