SMS Code

Multitap replaces a letter by repeated digits defined by the corresponding key code on a mobile phone keypad (This mode is used when writing SMS). For example: 2=A, 22=B, 222=C, 3=D... You can identify this code because you will see several numbers repeated.

You can decode this code in: https://www.dcode.fr/multitap-abc-cipher​

Bacon Code

Substitude each letter for 4 As or Bs (or 1s and 0s)
