Time after access form

I have a question about one thing that was leaving me intrigued. Why is the anti-spam system only functional for 15 minute or less?! APPORT 15 minutes I access it and I have it to enter again. Thus, it is possible to send manuals with the Internet connection that I have. There is no time necessary!
? I ask the moderators if it is not possible to spend this time for an hour or more to be able to send the files?!

How can I send the manuals without falling access connection?

Thank you

Welcome to the companion forum, it seems to me that the problem has it in your Internet connection since the page has a limit of 40 minutes or 200Mb of climb.

If you ask you to enter the antispam code ahead of time it is because either your connection does not support the climb and you run out of sufficient bandwidth or because the modem collapses.

All the best.
