What does the "block number" in the iota wallet represent?
My iota wallet displays something that I would assume to be a block number in the lower left corner: 291911
But being aware of the Tangle structure, I know there are no blocks in iota. What does this number represent? Bundles?

Does the Tangle enforce a tip-selection algorithm?
Can spammers use their own algorithm to non-randomly select tips — possibly then continuously confirming the same transactions over and over again while inundating the network? This was a recent assertion on Reddit that strikes me as false and I…

I've read in a few articles that the Curl-P hashing function was designed with known practical collisions, intended as a "copy protection" feature.
