* Function called from datastore with result from us looking for
* a UBlock. There are four cases:
* 1) no result, means we move on to the next keyword
- * 2) UID is the same as the first UID, means we move on to next keyword
+ * 2) data hash is the same as an already seen data hash, means we move on to
+ * next keyword
* 3) UBlock for a different CHK, means we keep looking for more
* 4) UBlock is for our CHK, means we remove the block and then move
* on to the next keyword
