A lot of events are basically just a circle-jerk mess and you should know that Mahjong is a notorious newfag-bait. Any event that actively is trying to get new people to join them is probably just /trash/ stuff or incredibly desperate for new blood because they have a terrible reputation. Case in point your experience.
Join something else, don't announce you are new, don't announce anything. Blend in and do not set yourself apart from the group.
