My two biggest problems are 1) Phone number requirement and 2) it blocks non users from visiting the website by forcing them to create an account first. Why the hell would they do that? That's the same problem Gab has and why it never got popular. They should just let people browse Parler without being logged in, that way posts from the website can spread faster. Blocking the site behind a registration with a phone number req will obliterate the traffic. It's like it's been designed to fail. Everyone on Parler should lobby the founder to remove the registration requirement for browsing the site
I suggest the elden ring subreddit
Also those are some big milkers
