If you really want our money, then offer to do something to earn it. ztrot was in a desperate state a while ago and he did a non-stop 72-hour(?) stream, wherein he played games and stuff by request. He gave people an incentive and was already known by many. How did you even think to use this place?
As for the homeless remark, lots of homeless people are shameless fucks or are scamming people out of their money. There are some who are genuinely desperate and are also nice to everybody, giving or not. However, for every nice person who realises that they can't force money for nothing, there are loads who slag off those who don't donate, will piss away their money on some crap or were stupid enough to get themselves into the situation in the first place. I don't think that slinging around words like "retards" keeps you out of the bad camp.
I'm appreciative enough of the situation that's portrayed, but there must be some welfare avenues left, even though Cameron's lot are shafting the working-to-lower-middle class as they see fit. I realise that "get a job" isn't very feasible in our climate, but unless you've fucked up seriously, you ought to be able to claim benefits beyond the dole. You're a familymaker and there's child allowance, spousal benefits and probably enough others if you look hard enough. If you've somehow gone and thrown all of that away, then how would people know that their donations won't also be thrown away?
Put simply, you're going to have a very hard time with persuading anybody on the Internet to throw their money at you. It saddens me that threads like this should exist, but the platforms which you've used aren't really helping your case. Crowdsourcing sites are for big projects, not begging. Video game communities, or forums in general, are not really good avenues in the slightest if nobody knows who you are and you look shameless as a result. That's just the way it is.
Good luck with picking yourself up. If you make a compelling case for yourself, then some of us might be swayed to chip in. That time hasn't come yet.
If you're just trying to scrounge for money instead of getting up and claiming benefits, then you're not welcome here.
