cannot imagine we have such few people which are interested to fight against HF. who has serious interest and willing to pay to get back a at least a portion of his invested money?
i've got serious interests, but i don't believe in group efforts when they'd have to be coordinated internationally, i'm afraid - even less so when it comes to law-stuff.
at least it's getting clearer (for me, personally) that i WILL ask for a refund instead of accepting some hardware at this point. and according to "my" terms of service, the asking-for-refunds-window started today and is open until january 15th, and i'm taking that time to (hopefully) do it right. i'm in contact with a local (german, as far as i'm concerned) lawyer to get some advice how to react (from me to hashfast, directly) in a way that's hopefully/kinda unimpeachable - asking for a refund in btc, full amount that i paid back in november. only afterwards i'll think about suing (or taking other legal actions), i.e. if that other stuff doesn't work.
