Jokerstash invite scam

[lon]

I've been scammed 3 times now of a total $120 trying to get an invite for jstash... this is not cool.
Some people say they are free but I can't seem to find..
All I can find is people and sites saying they are selling an invite like this place: jokerstash-invite.com(SCAMMMMM)
How in the world can I find an invite for this site??
Or do you guys know of a site comparable to jstash that doesn't require an invite??
Please, any info is much appreciated! Thanks
