Don't worry about it vindicated, whenever someone new or inexperienced posts about something like this, someone usually calls them a troll. Good luck whatever you decide to do about this situation.
echo the above, try and video it, and report it. And get out of there, its not a good place for anyone to be, let alone a novice who wants to learn.
Troll or not, who cares, i think some people need to realise not everyone is experienced, and shouting troll at novice type posters doesnt encourage the rest of us, who dont know everything, to post!
