As noted minor dribbles are common, even when the tank and lids are properly matched. Also, as noted, about the only sane thing to do is live with it. I generally use a water bath and do the agitation either over the water bath or sink, so any dribbles are harmless. I probably should wear gloves all the time, but generally only wear them when I'm processing in pyro. My hands do get rinsed however (or dipped in the print washer) any time they've caught any of the dribbles (with or without gloves!).
In theory, the stainless tanks, lids, and pouring lids are matched at manufacture, but easily become unmatched and mixed up in use. They are also prone to leaking if the tank or lid has been dropped and deformed slightly. If you have multiples, match what you have for best fit, mark them if necessary, and trade off the ones that leak excessively. Replace with new ones if necessary.
FWIW, my favorite tank is an Omega brand I bought new years ago. It leaks occasionally from the pouring lid, but not otherwise, and not at all if I press the lid on firmly enough. Sometimes the rotation angle between the two mating pieces matters, and a lid will leak in one position but not if it's rotated by some amount.
You could try twisting the lid on the tank until it binds. (this may make it difficult to remove too, as a warning).
