I have well over 2500 members. I sent out an e-mail notifying all members we may be making a move to a different service. I also notified Meetup they were not allowed to send my members any unsolicited political e-mails and they were not allowed to use my groups name without express permission of us, it is a registered trade name. Also they did this in direct violation of our groups rules. I have lost a number of members since they pulled this. They have damaged our reputation by taking a group founded on no drama into a political one.
Frankly I think we could all band together and look for a law firm to file a class action suit.
As it is I am contacting Forbes, Bloomberg and other News Agencies to let them know what Meetup is doing.
Let Meetup explain to them how they have become a political action committee on the backs of organizers who have helped them become what they are.
