This is called selective memory, we tend to remember the odd incident much more specially if it went against us. No poker platform can risk such manipulations as first of all these can easily be identifiable and exploited by players and secondly it will be very bad for the reputation which is everything in online gambling world.
The strange thing is that such selective memory works only in this room. At the same time, I am not accusing anyone of dishonesty or manipulation, I am only talking about my observations.
People see new platforms with skepticism anyway may be this is the reason. If you are playing at a platform for years, your mind has encountered the balance in variance distribution with the sheer number of cards dealt. I am confident that if you play enough hand there you will not even notice that.
Manipulating cards in real time requires much more complex algo and risk of exploitation is too high.
I am not supporting any platform (or opposing here) but just sharing what I think might be happening with you.
