I am using this service for more than a year. While I still couldn't manage to get more users.. but I have never faced any downtime etc. So, all the love and support for your guys.
Now, I want to re-invest my time into this community. I was researching for any method to sync my WordPress users with the flarum community and finally I found this extension called - WordPress Single Sign On (SSO)
link - https://discuss.flarum.org/d/21666-php-and-wordpress-single-sign-on-sso
I have also created a request thread on official Freeflarum github page here - https://github.com/gwillem/freeflarum.com/issues/128
Please try to include this extension or please let me know if there is any other simple or complex way to be able to use WordPress users data directly with Flarum community for the user syncing.
Thank you.
