Well, it appears Bux3 hasn’t totally gone. There was a message on the domain earlier saying that they were recovering from a database hack – not the first one either I think – and now the site is there, although not working correctly yet. I wonder how much damage the hack has done.
WorldBux, which was, the last I heard, also owned by the same company is still totally down. Also, Buxit.info has been down for several days now.
