is tube blaster pro dead ?

It does. thats what i use. although the limits are much higher like 75 subscriptions every 2 hours, lot less friend requests, capcha after every other comment unless you time delay it, etc. Its easy to gather ids and send messages though. So, It helps but only a little bit. You won't go viral simply using tubeblaster pro. I'd use it as an extra thing on the side.
