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.
