This is a good idea Sellange.
A new member must first upload a minimum set amount of Kb's, or Gb's, then seed that amount to a 1:1 ratio at which point their torrent client is given access to downloading.
After that, their downlaod ability would be dependent on keeping their ratios proportional much as it is now. Implementation of this could pose a significant programming challenge to Admin. !!

jannoyahoo = definitely 'hit & run' - listed as 'no' in peers and seeders per your snapshot - currently still not seeding
killer013 = not a 'hit & run' - currently seeding

The discrepancy shown in your snapshot may be resultant of comparitve locations and time of your snapshot:
killer013: Burkina Faso > West Africa > GMT 0
the5cardstud: US > North America > GMT -8
Or myriad other minor factors:
temporary power down of computer
temporary power outage
temporary computer shutdown to let it cool before resuming seed
Most importantly your post Initiation shows him currently seeding in both peers and seeders.

Actually I agree with you Roto.

I personally don't have a problem with leechers. I believe the vast majority are college aged kids with limited resources, having to share a computer, still living at home, or not in an environment where they can be completely out. And we have all been there at one point or another in our lives.
The problem resides in bandwith consumption. Especially when viewed as an overall statistic either weekly, monthly, or quarterly. When seen from that perspective the 'dead-weight' becomes a liability to the health of the torrent/swarm/site, etc.
With enough seeders who understand keeping the torrent alive and continue seeding to a 1:2 ratio the 'dead-weight' will become a mute point.

Another possibility to be used as an adjunct to minimum ratio's:

Post a list of the most serious offenders - the one's that by looking at their ul & dl numbers it's clear their intention is to download only. Post their username and IP addresswhich will allow seeders the option of blocking the IP from within their torrent client.
Posting IP address' in a public forum may not be a popular idea, but those whose intent is only to leech will certainly think twice, maybe even a third time, before continuing to enjoy the fruit of other's labor, without contribution of their own.
Another possiblity as opposed to posting the IP's in a forum is to give seeders the availability, via Admin. or Mod's., the availability to request a list of known serious leechers so the IP can then be blocked from within the seeders torrent client.
Keep in mind there are myriad reasons why some individuals ratios look skewed - so this certainly wouldn't apply to the majority. I'm talking about those who have dl'd 5G's and ul'd 0-500 Mb's.

What do you guy's think ?
