What am I giving away at the Mahjong table without meaning to?
More than you think, and most of it is habit rather than tiles. The table reads what you say, how long you pause, where a new tile goes on your rack, and whether you let a free Joker sit. The cure is not secrecy, it is consistency: say nothing about your hand, keep your tiles together, and do the same thing every time.

What you say
The loudest tells are spoken. I have nothing. I went the wrong way. Where are all the Jokers? Every one of those is a status report on your rack, handed over for free, and the last one also tells the table the Jokers are still out there to be drawn. The rule of thumb is short: while the hand is running, say nothing about it.
Wait is a word worth watching too. You are entitled to say it, and one wait gives nothing away. But each one tells the table the discard sat near something you want, and several on the same numbers make a pattern anybody can read. Know which tiles you could call before the next discard lands, and a wait becomes something you say only when you mean it.
How long you take
A hesitation before a discard says that tile mattered. A hesitation that repeats, from the same player on the same kind of tile, is a habit, and a habit can be read. This is the one tell that survives online, where nobody can see your face, and good players watch for it constantly.
Doing nothing can speak as well. A player who leaves an easy Joker exchange sitting on the table is almost certainly not building any more. At the courtesy pass, offering a number first tells the player across that you still have tiles you want rid of. Letting them speak first costs you nothing.
What your rack says
A gap between groups tells the table how your hand is built: how many sets are forming, where the pair sits, which tiles you are keeping apart. Keep the tiles shoulder to shoulder, sorted however you like, with no spaces between them.
Where a new tile goes matters as much. A drawn tile slotted straight into the middle of the rack announces a keeper. Put it at the end, discard, and move it into place later when attention is elsewhere. The same goes for tiles arriving in the Charleston: put each pass in the same spot every time and arrange them after your next pass. And if your Jokers always live at one end, every tile that goes to that end is noticed.
The tell is the habit
Tidying your rack does not show anyone your hand. Doing it the same way every week, with the same four people, eventually does. A consistent player is readable because the pattern is known, and what gets noticed is the moment you depart from it. So vary the harmless things, which side your Jokers sit on, where your pairs go, and keep the telling things, your voice, your hands and your timing, perfectly dull.
