I think the answer is


First we must

arrange the numbers into a $23\times 23$ grid. I have colored the numbers here black=1, white=0
The first square tells us to look at the middle columns which clearly spell "DELETE".

Deleting those columns and arranging the remaining numbers into a $17\times 23$ grid, we get
spelling "THIS TOO" in the middle cells as hinted by the second square.

Deleting those cells and arranging the rest into a $13\times 17$ grid, we get

The first and last three columns spell "Add 7 bits"
Deleting the first three and last three columns, adding seven bits and arranging the rest into a $18\times 7$ grid, we get the following picture where I have switched white $\rightarrow$ red (except the 7 extra bits are white).

  • $\begingroup$ That answer is correct! (The message that's "a bit harder to read" isn't quite right, though -- it's the first and last three columns.) $\endgroup$ – Deusovi Feb 8 at 21:13
