4 days was how long I lasted before they put the kibosh on. Tried creating new accounts but it didn't work... they got my whole IP tagged.
But now that I think about it... I finally got a VPN last night, for unrelated reasons. Maybe I should fire that up and see if it makes a difference on Filemail.
The VPN works. That's what I use to get around their 2-uploads per 24 hours.
