From what I read, RBBT is not on the chopping block for at least a few weeks, and that's only if there aren't other coins with lower volumes.  RBBT volume there is currently around 170 LTC/month.  If it stays consistent, quite a few other dying coins will get the axe before RBBT.

That being said, the coin does need some help.  The three biggest issues I see are...

    * One of the biggest RBBT pools, hash.so, has had "issues in the backend" for the last three days.  Doesn't help the coin much when people try to mine it and see zero results for their efforts.  Most of the other pools appear dead or dying and who wants to mine at a dead pool?
    * The developer appears to be MIA.  Without any direction/support from this end, RBBT won't last.  Anyone care to step up and take the reigns?
    * Buying support seems sporadic, although quite possibly tied to problems stemming from the two issues listed above.

In my opinion, RBBT isn't dead, but it is definitely stalled with some major obstacles in the way.  Looks like it's up to the community to decide if we can overcome them or not.
