TBH I don't think just cause someone don't have a box disqualify him from not getting into any site..for example I seriously wonder sometime why people who giveout invite to FTn ask for seedbox prrof cause IN my opinion tracker like that are gonna help people with low speed or those who cannot afford seedbox more then to the people who can and survive on
SCC..I personally have given my invite to a invite who is a real good forum user but have not used seedbox in long..he got like 1Gb upload there but I am perfectly happy that he is getting what all he want and not just having the tracker for buffer whoring or showoff..
now why I wrote this is cause If we have permanent SB as criteria for all our invite we are neglecting many of awesome users..and if it was the criteria I would have not got my 1st torrent tracker yet :P :P...
now the scenario is little diff for tracker like what(tough to seed)...SO the one who apply for any giveaway and give those Sb which they have got from giveaway as proof(also mention it in there post) are just trying to show the user that they can get initial buffer which will help them survive the tracker and the invitee don't need to worry about there ratio...I am sure if you are inviting someone you don't want to see him having a ratio of 500 but you prefer him to grab/download 100Gb with ratio of 1 to 3...
so overall IF the user mention all details about his box(from which giveaway he got it) I don't think it's even slightly wrong...ya misleading someone to get a invite is always wrong...
PS. for example I have about 100Gb down on waffle and some 250Gb up in there now..even if I don't use a box on that tracker I won't have ratio problem for long now..and even if I do I can always upload some stuff to keep up the pace...same goes for most of the other tracker..
