Honestly been going back and forth on this for the past few weeks.
The free tiers on most of what I've tried are basically useless — you get just enough to see that real people are there, then hit a wall the second you try to actually message anyone.
I've noticed a big difference between platforms that moderate actively and those that don't. The ones that don't tend to become unusable within a few months.
Any input is appreciated, whether positive or a warning. Both are useful at this point.
