Do you know where else I didn't see your name? That would be in any of the posts highlighted above, to correct the statements and set the record straight that this man had NOT been removed from this group. One of the biggest mouths on your page stated it as fact, and your silence certainly implied the statements were true.
Where does your confusion with "Made up name games" come into play? Surely, being on the Internet, you have heard of Twitter, SnapChat, reddit, chatrooms and message boards that give the option to use a proper name, or a screen name of your choice. So, yes, please do continue to address me by MrSmith.
Lastly, thinking anything stays private within a group of over 1000 people is pretty naive, good luck with that.
