An online community has three moderators: Doorknob, Kevin, and Emrakul (in no particular order). In between making posts on meta, they decide to set up a code for their private communications, and start sending secret messages to one another. First Doorknob sends Emrakul this message:
$2211+1211=111+21+11+2111+1+1112+221+121=1221+2111+2122+2111+1=1112+1121=1211+121+2122+2122+2111+1222$
Then Emrakul sends this one to Kevin:
$1211+121+1121+221+121+1+2212+21+1211=1112=1121+21+1222=21=2212+2111+2=21+12+2212=21=1221+21+221$
Finally Kevin sends this to Doorknob, closing the circle:
$1112=2122+1112+2112+121=21+2121+2121+2122+121+1121=21+12+2212=2111+1+21+12+2+121+1121$
Can you decrypt the messages?
Answer
Yes.
Quite simply:
The ones and twos correspond to Morse code dots and dashes. The plus signs are letter separators, and the equals signs are word breaks.
That gives you
1. ZL SNIBEVGR PBYBE VF LRYYBJ
2. LRFGREQNL V FNJ N QBT NAQ N PNG
3. V YVXR NCCYRF NAQ BENATRF
Then all you need to do is
A 13-place Caesar shift (rot13)
To obtain:
1. MY FAVORITE COLOR IS YELLOW
2. YESTERDAY I SAW A DOG AND A CAT
3. I LIKE APPLES AND ORANGES
