Well, I think this thread belongs to the scam accusation board since we are talking about their scams. Apart from the two threads you mentioned from the Bitcointalk forum, there are a few more that you can list here.

>> Fixedfloat is scamming me for 8000+ EUR IMPORTANT PSA!
>> fixedfloat holding my funds $1000
>> FixedFloat.com stole my funds

If you collect data from all over the internet, you will find dozens of accusations against them.
