They are still operating.
Do not use.
Yeah and by now they should really be handed a negative trust for their shady activity. They haven't refunded anyone who hasn't gotten their transaction confirmed like they promised to and neither have they logged into their bitcointalk account since 3th December(2 weeks ago almost), when before all this happened, they were logging in daily and active on their own thread.
I remember there was one guy saying that confirmtx contacted him for ICO creation services.
How absurd if that is true, because quite frankly who would buy into an acceleration business that probably just copy & pastes txids? It makes no sense.
