This has been on my mind lately and I figured this community would have solid input.
Safety and privacy are also big concerns for me. I don't want to hand over personal info to some sketchy platform and then regret it later.
I've noticed a huge difference between platforms that moderate actively and those that don't. The ones that don't tend to become unusable within a few months.
Feel free to share whatever has worked for you, even if it's not the obvious answer.
