"Actually I sold ABC a couple of days after that post when it broke support..."
Given your previous advice to "stick with it" because "the trend was still up" a couple of days earlier....Did you post you were intending to sell ABC PRIOR to selling? If you didn't - you may well be for the high jump. I am led to believe the regulators take a very dim view of this type of behaviour and I'm also led to believe a poster's anonymity is not safe on here if there has been any illegal behaviour.
If I was in your shoes, I would be very worried Skol.
