Ok, so let me begin. I signed up like 1 year and 5 months ago, creating an account on mining.bitcoin.cz, for the purpose of mining, of course.
For about 2 months I used 'miners' on several linux operating servers and reached the ammount of 1.51 BTC. Its value was pretty low back there and I left all this stuff, doing something else.
A few moments ago, I checked the BTC value and I was like WOW, WTF. Didn't even remember how much I had on my account, so I logged in to see it.
But surprize, 0, nada, nothing. And a payout log of 1.51 BTC to this address: 1PJ192n9gs13nHNNSz4Bo5AMoYGBrUvK1N, at 10-16-2013.
No, it wasn't me doing that, I didn't log in since 1 year 3 months ago, the mining process says it just this way.
And no, nobody else could know my username/password to that.
Now, what in the hell just happened? Did they just stole my work and money or I'm too stupid to see what's going on?
Please, if anyone can help or know anything about this, say a word.
I don't even know where to complain, there's no Support section.

In urma cu aproximativ 1 an si 5 luni mi-am creat un cont pe mining.bitcoin.cz si am folosit mai multe unitati de calcul pentru a "mina"
Am reusit intr-un final sa 'produc' 1.51 BTC. Valoarea era foarte jos pe atunci si am renuntat la a mai continua. Zilele astea, realizand cat de sus a urcat valoarea, am vrut sa vad ce-i cu contul meu. M-am logat si surpriza, zero, nada, nimic. Plus un log de payout catre adresa: 1PJ192n9gs13nHNNSz4Bo5AMoYGBrUvK1N, in data de 16 octombrie 2013, desi eu nu am mai folosit contul de 1 an + si in mod evident eram singurul care stia username/password.
Acum ce sa inteleg, cine m-a furat si ce dumnezeu se intampla?
