At first, the site had the Freebies available even for guests, so anybody was able to download without registering/loging-in…
but this caused a little problem. Some web crawlers are taking a real fun downloading the attachments multiple times, for no reasons… and they persist… it loads the server a lot in no time, it’s like spam in the serverside.
i can not afford to see my host bandwidth/usage overused only because of a clash in attachment downloads, so the simpliest solution i could apply is to force people to be logged-in to download.
This is not a real problem right now as there is not much people visiting the site… but there is more crawlers visiting the site than guests, so i can not take a chance.
sorry for the ones willing to have no account, this is my solution.
