No one I asked about their program gave a full clear recommendation. It's always a "you get out of it what you put in it" type of answer. This sounds like they didn't think it was worth it and don't want to admit it.
Does anyone have experience or knowledge of whether participating in their paid programs is worth it?
Something I have learned in life is never waste time on events pitched as "meet interesting people". Interesting people don't go to that kind of event.
Go someplace interesting people have a reason to be.

Whether it's a "scam" is a bit subjective. There's a decent chance that once you pay the fees, you really will be granted access to online forums and/or chat servers and/or IRL events with the people listed on the web site (there's a good chance the bigger names are getting a cut of the program's profits). However, it's also possible to meet and interact with these sorts of people without having to pay an entry fee and join a club; look for events on LinkedIn or MeetUp or the like.
