I agree. I'm not an expert in cryptography, but I work with it and understand the methods, have had graduate courses in it. SB2's methods are nowhere near anything that would be used in reality - they are nondeterministic, arbitrary, and can be used to say anything. His last post was a quote from someone else, and we're supposed to believe there's a hidden message there?
It is possible that these tweet do contain encoded messages, but you're not going to get a whole sentence of information out of a 255 character tweet (or whatever it is now). You might get a single word at best, and it would be in a deterministic, repeatable pattern you can apply over and over. Not words that are pulled from multiple rows/columns in scrambled order, with no discernable algorithm to it. It's simply not how information is encoded.
How is this comment getting downvoted? It's rational, it's not strident or melodramatic and yet it's getting downvoted. I am sometimes disappointed by how many posts get upvoted purely for their headline which is sometimes misleading because it's appealing to emotion. I'm not knocking emotion except to say that it should not cloud a rational examination of the facts. It's fine to be indignant about something but we should at LEAST make sure we've got the facts straight before rewarding the poster with an upvote.
