In other words, instead of clear and accurate information from the GM, which would allow for proper analysis, there will be a fun competition of "who can twist things better," because the fact of the block itself won't tell anyone anything, except for the blocker, and anyone can write anything they want in a note. You are proposing a game format based on players making up anything and suggesting that they switch off their brains, simply trust, and have no facts except for a dubious clue that still needs to be correctly interpreted. It's your choice, of course, but I think such a game format is, to put it mildly, extremely unsuccessful. Yes, I edited the post a bit; I don't like arguments, although sometimes I really want to.
