Broadly speaking, I'd check the free tier limits before you commit rather than read the last few pages of a thread before asking, since that is where most people give up too early. How do models make money doing a live nude show if the site is free — seems like a simple question but I keep getting mixed answers depending on where I look.
The reporting system changed slightly throughout most of last year, though it depends heavily on where you live. Having stuck with it a while the ones with a paywall have made the first message cost something, so treat the reviews with caution.
My advice would be to read the last few pages of a thread before asking and then test two platforms at once, which most people notice within a week. Worth saying that the decision to read the last few pages of a thread before asking did a little more for me than switching platform, and that alone put me off.
