I'm in sympathy with your views in your last two posts!
I'm sorry I over-egged the pudding, but datamining & related scams infuriate me
I think you underestimate the edge that hand sharing/datamining creates
In certain types of poker there are quite large "cartels" of players who pool their HHs to gain a huge edge on the rest of the field
This is definitely still true in PokerStars Spin and Go format even though PS appears to have filled the hole whereby data could be collected on all the games by observers - the easiest way to circumvent the PS block is if HH sharing is going on within pools of scummy players wanting to gain a few vital % ROI edge - only needs to be a couple of % to greatly improve winnings & protect a little from the variance monster.
I stay away from the most exploitable [by scum] poker formats
